| How to Deal with Rejection from Family Posted: 18 Jul 2021 05:00 PM PDT Family rejection may be one of the hardest things a person can go through. It's understandable to experience waves of hurt and grief, and these are feelings that don't go away overnight. If you're struggling with family rejection, know that you've made an important first step to heal by looking up ways to cope! There is a lot you can do to work through your feelings, accept what you can't change, and ultimately come out of the process stronger and more resilient than before. [Edit]Give yourself time to process your feelings. - Acknowledge your emotions and don't be afraid to cry. It can be really hard to look at feelings of sadness honestly, but avoiding your feelings won't make them go away. Listen to sad music, cry, and be honest with yourself about how you feel. Rejection hurts no matter who it is, and when you've been rejected by a family member, those feelings can be magnified. Know that it's okay to admit that you're sad, and might make the road to happiness a lot easier down the line.[1][2]
- Try not to linger on your feelings for too long, though. After listening to a few sad songs, turn off the music and go for a walk! You don't have to feel everything at once to get through this.[3]
- As hard as it is, remind yourself that you can't control your family's behavior. You can, however, control how you respond to it. Focus on your own emotional growth to come out of the grieving process feeling resilient.[4]
[Edit]Journal your emotions. - Writing down your feelings can give you some clarity. You may feel a lot of different things about your family's rejection, including sadness, anger, and shock. Invest in a journal or notebook and use it to write down how you feel. Take even just a couple of minutes each day to process. As you write, you'll hopefully understand your emotions a lot better.[5]
- Use the journal to rebuild your self-esteem after the rejection. Family rejection really hurts. To prevent it from affecting your self-worth, write down all the things that you like about yourself. Next time you feel down, look at your list![6]
- Journaling can also help you recognize certain triggers. Read through your old entries and take note of the days you felt especially sad. See what they all had in common, and look at what changes you can make to avoid those triggers.[7]
[Edit]Repeat positive affirmations when you're feeling low. - Remind yourself that you will get through this! Motivational phrases can be an easy but meaningful way to snap yourself out of a particularly rough place in life. Use phrases like "I'm worthy of love and respect," "I am a talented and beautiful person," and "I am strong and can get through anything." Even if you struggle to believe them at first, saying these phrases in your head or out loud can encourage you to see yourself and your situation in a positive light.[8]
- Other positive affirmations you can use include "I'm capable of great things," "I deserve to be treated well," and "I love myself."
[Edit]Limit negative thinking as best you can. - Don't let thoughts like "I'm a horrible person" play on a loop. It can be really hard not to blame yourself for this kind of rejection, but try not to let those thoughts take over. Anytime you catch yourself being really down on yourself, reframe your thoughts from a more positive perspective. If you think something like, "I'll never be happy again," replace it with something positive. Try, "This is really hard, but I know I'll find happiness again in the future!"[9]
- Thinking negatively can prevent you from finding happiness because you stop noticing the good things in life.[10]
[Edit]Reframe the rejection as something positive. - It may be healthier for you to not be in your family's life right now. This is especially true if you experienced emotional or physical abuse. These behaviors can leave lasting effects, and it may not be safe to forgive or reconnect. If you experienced a toxic or abusive family dynamic growing up, remind yourself that you're safer without them in your life. Look at their rejection as an opportunity to surround yourself with people that make you feel safe, respected, and loved.[11]
[Edit]Focus on self-care. - Take care of yourself to recover from the rejection. Eat healthy, nutrient-rich foods. Get plenty of sleep (7-10 hours every night) so that you feel well-rested and ready to take on each day.[12] Exercise to destress and keep your body fit and strong. Take up new hobbies that enrich your life, like playing an instrument or joining a book club. All of these practices make your life feel like it's headed in a positive direction, even if you're dealing with the pain of family estrangement.[13]
- Avoid turning to drugs or alcohol to feel better. They won't help in the long run and can leave you feeling worse than before.
[Edit]Seek out close relationships elsewhere. - People don't have to be your flesh and blood to be family. Make close friendships and seek out healthy, compassionate relationships with romantic partners. Choose friends and partners that make you feel safe, cared for, and loved! You want to surround yourself with people who make you feel good about yourself.[14]
- Have a movie night with friends if you used to enjoy movie nights with your family. Invite your friends over for a family dinner. You can even spend holidays with a group of close friends!
- To make new friends, try volunteering in your community, joining a local book club, or connecting with others online.
[Edit]Talk about how you feel with someone you trust. - Call a friend or go over to their house to talk with them. Let them know about what you're experiencing and ask if you can get their advice or process what you're feeling with them. A good friend can give you words of support and remind you that there are people out there that love and care about you.[15]
- If you still need help processing how you feel after talking with your friends or don't know a good person to talk to, talk to a professional instead. A therapist or counselor can give you strategies to cope.
[Edit]Set boundaries if your family continues treating you poorly. - It's possible that your family still communicates with you sometimes. If they treat you badly, tell them that their behavior is unacceptable. Next time they put you down, tell them how you feel. Say something like, "It hurts when you speak to me that way" or "I can't continue this conversation if you're going to treat me like that." If they don't respond with a change of behavior, it may be time to limit your contact with them for the sake of your emotional wellbeing.[16]
- If they make you feel unsafe or don't respect your boundaries, it's okay to take communication with them off the table. As painful as it may be, going no contact might be the best decision for your safety and mental health.[17]
- You don't have to make your decision immediately. If you're not sure how you feel, take some time to figure out the boundaries that will make you safest and happiest.[18]
[Edit]Work through your emotions with a counselor or therapist. - A professional can give you specific strategies to recover. They can also give you an outside perspective, something that a trusted family friend may not be able to give. Search for a therapist or counselor in your area using websites like https://.psychologytoday.com. Look for a professional that specializes in family estrangement to find someone who can provide tools to process what you're feeling.[19]
- Sometimes it takes a little bit of time to find the right therapist or counselor. If the first one you see isn't a good fit, don't get discouraged. Try to find another professional in your area that can be a better help to you!

| How to Learn About Engines Posted: 18 Jul 2021 09:00 AM PDT Engines are complex machines that power cars, motorcycles, airplanes, boats, and even factories. You could even say engines make our entire way of life possible! They're fascinating machines, so whether you want to do some car repairs or are just curious, it's only natural to want to learn more about engines. Luckily, we're here to help and answer any questions you might have. [Edit]How do combustion engines actually work? - Engines burn fuel to release energy and produce motion. Basically, fuel enters the engine through an injector. The spark plug then ignites the fuel to release energy. This energy turns pistons in the engine, which makes the crankshaft turn. The energy then transfers to the car powertrain, which spins the wheels for motion.[1]
- This process is how an internal combustion engine works, the type that is in cars and most other motor vehicles. But there are also different engine types, like steam, water, or air-powered ones.
[Edit]What are the parts of a combustion engine? - Engines are complex machines made of many different components. These parts all work together to make the engine run. Some of the parts and their jobs include:[2]
- Valves, which open and close the exhaust and air valves to let fuel and air into the engine.
- Pistons, which compress the gas to make it ignite.
- The spark plug, which ignites the gas to power the engine.
- The crankshaft, which spins and produces power.
- The engine block, the main support structure for all the other pieces of the engine.
- Combustion engines are usually arranged in a V shape, with a row of cylinders on each side. A V6 engine, for example, has 6 cylinders with 3 on each side.
[Edit]What is the most important part of an engine? - No single piece is more important than the others. Every part of the engine needs to work properly for it to run. If any part isn't working, then the engine will either run poorly or fail to start altogether. The whole thing needs to stay in good working condition for the best performance.[3]
- Not all car problems are problems with the engine. For example, if your battery is dead, the engine won't start. But this doesn't mean there's something wrong with your engine.
[Edit]What do combustion engines need to run? - All engines need fuel, air, and a spark to get started. These are the main components of the combustion process that produces energy and makes the engine move. Injectors bring fuel and air into the engine, and the spark ignites the mixture. To continue running, the engine needs a steady supply of fuel and air, because the combustion process will stop without a mixture of both.[4]
- A broken or dirty spark plug is a common engine problem. Without the spark, the engine can't start.
- Oil isn't part of the combustion process, but an engine can't work without it. If the engine doesn't have enough oil, the moving parts will lock up and the engine won't run.
- Every gas car needs to get an oil change.[5]
[Edit]What other types of engines are there? - There are many types of engines and they all work a bit differently. Internal combustion engines are probably what you think of when you think of an engine, but there are lots of others. Here are a few of the other common ones:[6]
- External combustion engines, where the fuel burns in a different location outside the engine. A steam engine falls into this category, since the water is boiled in a different spot and then fed through the engine.
- Reaction engines, also called jet engines. These spin very quickly to force air out the back end, creating motion.
- Electrical engines use magnetic or electrical energy to produce vibrations. These vibrations when spin a turbine to produce power.
[Edit]What's the best way to learn about car engines? - Reading your car's manual is best to learn about your own engine. There are lots of similarities between car engines, but there could be important differences too. That's why referring to your car's manual is the best source. This will include all the repair and maintenance information that's unique to your car.[7]
- The owner's manual should include a diagram of your car's engine showing its main parts, as well as maintenance information like the correct oil type.
- If you've lost the manual for your car, contact the manufacturer for a replacement. You might also be able to find the manual for your car online.
- Reading auto magazines and books or watching videos works too. Your car manual is great for learning the basics of your own engine, but it doesn't have a lot of information about how engines work. Car magazines, books, shows, podcasts, and videos are all great sources to learn about how engines actually work. These are great sources to learn about engine operation and repair.[8]
- Magazines like Car and Driver or Popular Mechanics have lots of great articles about engines, and cars in general. Their websites are also helpful.
- There are tons of YouTube channels focused on cars that show all the steps for any kind of engine repairs you might have to do.
- It's best to stick with sources made by people who actually work on cars, like mechanics. This way, you'll know the information is coming from someone with experience.
[Edit]Can I work on my car engine myself? - You can definitely do simple work yourself if you're careful. Some simple tasks including cleaning or changing the spark plug, tightening the fuel cap, and replacing air or fuel valves. You can make these repairs yourself without a lot of experience and simple tools. Bigger jobs like a full engine replacement are better left to a professional.[9]
- Even if you're doing simple work, always follow a good source like a mechanic's video so you know the right process.
- Working on newer cars is a bit more difficult than working on older ones because of all the electronic parts in modern cars.
- If you're not sure about your automotive skills, then it's best to let a mechanic work on your car instead. If you make a mistake, then it might not be safe to drive your car.[10]
[Edit]Is anything bad for a car engine? - Yes, lots of driving and operation habits can damage your engine. Like all machines, engines need proper care and maintenance to run smoothly. To get the most out of your engine, follow these habits:[11]
- Let the engine warm up before using it.
- Rev smoothly so the engine doesn't crank too hard.
- Keep your fuel level above 1/4 tank so the fuel pump doesn't clog.
- Don't carry more weight than the engine was designed to handle.
- Perform regular maintenance to catch any problems before they get worse.
- If you want to learn more about engines and maintenance, you could always take some classes at a local technical school.
