When you're sad, just look into the mirror and tell yourself, "You'll be okay."
When you feel like crying, JUST CRY!! You'll cry for hours, days, weeks... But you'll eventually stop crying by that time you've decided to stop, you have to stop.
When you're angry and don't really know how to release your anger, just take a pillow, put it on your face and shout as loud as you can. Actually, people can still hear your voice but you'll tend to think that no one is hearing.
When you have no one to turn to... Turn to God and talk to him.. He'll be there He'll answer everything if you put all you heart into it and have faith in Him.
