i dont know much about this... personally i have a problem with eating, not because of weight.. but i just simply wont eat - and i'll forget to eat, i dont get hungry alot of times...
we have to take care of ourselves though, eat healthy foods...

stick around here, im sure there has to be someone here that can give you some advice on this, i just wanted to say hang in there... sometimes when we are younger our body will fluctuate with weight... and when you get a little older the weight could come off... i've seen that happen a few times... i guess its just the hormones making our bodies process things differently and when the hormones settle down the metabolism can get back to work ...
but i dont know much about this so i just wanted to send you a hug and encouragement... i hope someone with more experience can chime in for you, perhaps a lady... (im a guy)

take care of yourself
