Hi & Welcome!
I'm 5'3'' too. ^_^
I've never officially loss my baby fat. Hated PE in K-12. Painfully shy and terribly negative toward myself. Never had any close guy friends (just friends of my friends). Never had anything close to a romantic relationship. I've alway struggled with my image problem. I could never relate to other girls my age. I often think I'm mentally ill for not being able to make friends with other people and being hateful toward other girls with better bodies. I hate clothes shopping and going outside because I don't want to be look at/judged.
I'm going to school too, but I'm an engineering major. I am a dork and have zero taste, as in I'll eat anything that my stomach agrees with and listen to anything that doesn't give me a migraine.

...lately I've been listening to Rob Thomas.
Sorry for making this so long. I was excited to read your post because I could relate. I've decided not to give up on trying to enjoy life. I'm older and wiser and determined to live life on my own terms (I'm living on my own for the first time in my life since August). ^_^ . I'm changing my ways. Toughening up and learning to love life.
I hope you still at 3FC because the people here are immensely encouraging and caring. They're happy to offer any advice, comment, or motivation. (I've been here also since August). Find a support forum that you like and post away! (Careful though, it could be addicting!)...
Cheers!
