Jayson, your situation and mine are different, but I'll tell you about myself and maybe it will help.
Throughout my teen years I was always skinny and uncoordinated. Could never do any sports, hold my own in any sort of fight, etc. I really stood out, got bullied, etc.
But as I went through those years, I developed as a person. I discovered what I liked - books, movies, TV shows, activities, etc. I discovered what I was good at (computer programming, science) and what I liked doing (bicycling, theatre productions, card games). I found a few friends with similar likes. As I got older, the ways in which I stood out as different became less important and the ways in which I could be true to myself shaped a more positive self image.
Good luck, Jayson. I hope this helps.
