Hi everyone

i'm 13 years old, and for as long as I can remember, people have always commented on how skinny I am.
As most of you will know, it's the summer holidays at the moment. Both my parents are working, so I haven't been able to get out of the house much. I clean everyday, and walk to the shops and stuff. I eat quite a lot of junk. I have a phobia of being sick... I think if I eat too much of something, or try something new, i'll vomit, so I won't eat.
Only recently, i've noticed I seemed to have gained weight overnight.

I've been getting diarrhoea quite a lot, and sometimes I look thin again, but most of the time my stomach is big and squishy.
At first I though it was bloat, but my stomach wouldn't be fatty, squishy if it was.

It's really depressing me. I get picked on a lot, and I really don't want to be fat. I know that sounds really shallow, but I just don't want to be.

I've started skipping meals, and only have a two bars of chocolate everyday, and lots of water.
Any other food I eat, I immediately go fat.

Please, please help!
