I'm so sad to hear you're struggling at the moment surfergirl2, and you're taking the right steps by talking to your doc.
I had the same problem about a year go now. My friends were all skinnier than me and it would really get me down. Anyway, they turned out to be complete and utter cows. So, I dumped them all!! EVERY LAST ONE!!
No-one deserves to feel unworthy of friendship, and NO-ONE should be, well, bullied for how they are. So, I kicked them all to the kerb. Best thing I've ever done!!
Surround yourself with positive things and positive people, who you love you for you and don't pick at you for how you look.
Look after your mental health, and the rest will follow. Trust me, it will happen.
Keep your chin up.
