My gorgeous 12 year old daughter has been acting very depressed since shes been in fifth grade, She's in sevent now, She's always talking about going on a diet, she barely comes out of her room, Shes been crying herself to sleep at night,Whenever I try to talk to her, she gets either very angry or starts cying. She's 5'9 and 145 pounds she's always talking about her wieght, I tell her she a normal wieght, but then she starts crying. What can I do, Is it my fault she like this,Maybe it's her peers, all I want is a improvment.
