be more confident

I’m usually fairly confident, more so than when I was in high school, but when I’m faced with talking to someone I want to impress because I like them, I clam up and lose my confidence. Having this selective insecurity has resulted in me not feeling able to go talk to this guy I really like. He’s gorgeous and I don’t feel I’m pretty enough because I have a weight problem. Supposedly, he’s noticed me anyway, but I don’t buy it. I keep feeling that if he looks at me, it’s because he’s disgusted. I know that we make up things in our own minds and he may not feel that way, but I just can’t help it. I have no problem striking up a conversation or something with someone I don’t care much about, but if it’s a hot guy I really like, I just can’t make any move. Also, I’m fine if I’m approached, but I can’t do the approaching. God I suck…
