14 year old girl average weight

With everything thats going on, Im not dealing with things very well. Im concerning my boyfriend. He sees me slipping into depression. BTW, Ihave a history of depression...Im mild bipolar. A few years ago when I was going through my divorce and restarting a whole new life over (thrown into the world as a "newbie" at 30) I was a mess. I didnt sleep at all for 4.5 months - not exaggerating, my mother almost committed me. I didnt eat anything except a couple of glasses of milk a day for like 2 months. Needless to say, it was bad.
