Why don't I feel? Please help!?

I know this probably sounds weird but I only have two emotions. That would be anger and sadness. I have anger issues and all but that doesn't explain my sadness. I'm 13 and my parents are divorced. I used to cut when I was 11 but stoped. Also I am battling anerexia. I am getting help for that. But I still don't get it. Nothing is going right in my life well that's just what it feels like. I don't want to have depression or anything. But everyone said I might. I just doubt that because I don't want it to be that.
