Ever feel like you don't have what it takes? Options

[acenova]

Ever just feel down, like you're a loser with a wasted life? I'm 20 yrs. old, in college, never got great grades, but always good enough to pass. I've had jobs before, but never have money. I model, but for some reason feel inadequate in comparison. I have a beautiful, wonderful girlfriend that I've never been so happy with, and I don't feel I deserve her. I would do anything for her and for any of my friends, and I've always treated her the best that anyone has ever treated her before. Why is it that I'm scared I'm going to lose her? Why do I feel as though, even though her past boyfriends were asses and ****ed her over, I don't match up? Why is it that I feel that my material things and my lack of organization in life make me inadequate as a human and not fit to date this girl? I'm usually a fairly confident guy, I don't have it all, but I've got it pretty good. Yet realizing this, telling myself this, I am in shambles, and slowly becoming more and more insecure. Anyone have this??? Anyone get over this????
