I hate my family & want to move out..what can i do?

You can either wait until you are 18 years old and can move out of the house or go off and live on your own again. You are obviously wise beyond your years as you state in your additional details and your parents aren't worthy of your respect and love. As an unskilled 15 year old struggling with depression and an eating disorder, you will probably thrive out there on your on. At least your imperfect parents won't be around to cramp your style anymore.
