Help!! my life is falling apart.?

Well it all started when my parents got divorced. Now my and my brothers live with my dad and they are always fighting with me cause I still can't get over the divorce. Cause of this I fell into the arms of my girl friend who is also a drug dealer. I began to experimental in recreational drugs and one time when I was doing this I made love to her and then she got pregnant. This of course made my situation with my family worse and I was kicked out. to top this all of I am now anorexic. what should I do I have lost all hope and I am now turning to you people of the internet. Don't let me down.
