Work hard to deal with thing. You have it and the problem it brings. When you finally get control of this problems. Everyone around you seems to watch you in a different ways.
You never learn why it happened to you. Work more harder to make dreams come true. If you did fall again, get up on your feet and try again. It's part of life. Don't give up on yourself.
There's a lot of problems in life. Life is built on a lot of problems. Try to handle it by yourself. Don't always call on someone for help. You should help yourself to stand up on your two feet.
Go through life willingly. Even if it feels hurt and pain. Suicide is a never answer. It won't solve anything.
Treasure your life. Be strong and move on. Do not hurt your love ones. You can do it, sure you will.
