Does this sound like I have depression to you?

Okay well lets start by giving some background info: i'm 13 and a male and live in Pittsburgh Pennsylvania. I'm in 7th grade now and I moved her in 4th grade from Gainesville Florida. I miss it very much. I have low self esteem and am very weight conscious. I'm thin but I deal with over eating and am getting over bulimia (by myself). Well I have a pretty good family. I live in a nice house and I guess were wealthy. Like im writing this question from my iPod touch. Well when I moved her I was kind of a nerd. I didn't know what was "cool" or socially accepted.

And when I came to school the sadness would come and frankly, looking back, I have no clue how I survived. A lot days I would fake sick so I didn't have to deal with the pain of school. In the middle of 6th grade I tried to join the "popular" group. I guess I kinda made it in. I totally changed myself but I knew they weren't my real friends. Around that time I began to watch all seasons of the office or FRIENDS online and it kinda made me feel like I has real friends. I did that a ton in the summer between 6th and 7th grade. Over that summer I also most severly developed my bulimia. I hated my sel
