Very unsure about [m]yself

So I've never really had good self esteem growing up and I'm trying to deal and overcome some of these issues. I was never really invited to parties, never been a ladies man. I had a girl friend about two years ago and it was really self-lived. Just want to know what y'all think.

*EDIT - Don't state the obvious and tell me I need to lose weight. I've been going 5 times a week for 2 months now and watching what I eat. Guess my age too, I'm pretty sure you'll be surprised.
