What can I do about my situation?

You really should consider some professional help with depression from the symptoms you are describing. You might find medication can help stabilize your emotions.

you could also benefit from an online support group with compassionate people

you could also try these life style changes to balance your life.

a high protein low carb low sugar diet with small healthy meals or snacks every 3-4 hours can help stabilize the roller coaster effect on emotions of a high carb diet.

Exercise like walking yoga or calesthenics or qi gong can help energize your life on a daily basis (see youtube for instruction)

soft soothing instrumental music can help you sleep at night.

helping other with projects or volunteer work can give you job experience and reduce the focus on yourself and increase the sense of dedicating your life to helping others.

Mindfulness sitting quietly following the breath, letting your thoughts go by.

Showering is important for emotional well being. If you keep your body clean every few days, you will feel better. We all face challenges but we need to take responsibility for our own lives and accept that we have the power to change our life. We may not feel it today but somewhere inside us is the power to be ourselves.

You have a gift hidden inside you that is crying to come out and help the world. Try to do what you can to find ways for it to express itself in the world.

Painting or drawing can help get by the blocks.

Those are a few suggestions. If you look you will find the ones you need.

If you make yourself stronger then the taunts of others will not be as powerful. If you are being physically abused then consider calling abused women's groups in your area.

before you do that try to improve and strengthen yourself and see if your family situation improves. If you stop reacting to other people then maybe they will not react so much to you. It is worth a try.

I'm really sorry /: I would say just try your best to be positive. Don't let them see you break don't give them that satisfaction. As for your friends, if they're no good for you then cut them off. Try talking to new people. Make online friends (be careful) It definitely helped me. Youll find more people your age. Remember these things take time. Keep to yourself, don't talk or be seen unless absolutely necessary. Just take it day by day. If you ever need to talk email me (I'm a teenager too.) But pray if you believe in God, and have faith. When school starts back focus real hard on your grades you'll make new friends, not gonna lie basically everyone is gonna change, even you. But don't kill yourself. Youll get through I promise you're better than this. Stay strong and do NOT give up keep your head up so you can look back and say "I made it". I wish you luck! Warm hugs <3
