I don't know why but I get so uncomfortable around good looking people (of both genders). I already know I have poor self-esteem but I get really really really anxious around good looking people. I just can't stop comparing myself.

Because of this I avoid going to so many places that I know attractive people will be around. Especially at school events like dances/ceremonies or something where everybody will be all dressed up. I feel like everybody looks over to me and thinks "ew what is she doing her?" and judge me.

When good looking people talk to me I want to crawl away into my shell away from everybody. I want to put a paperbag over my head and just leave. I can't even look at them in the eye because I constantly think they are judging me. And most of all I don't want to be caught around these attractive people. I feel like if other people see them with me then other people will think bad of them for being seen with such an unattractive person like me. I don't want to bring their rep down just because I have this issue.

Another thing is that I made an online friend and turns out she actually lives really close to me and wants to meet up with me. But the thing is that she's really pretty and it's making me really anxious. I want to tell her no I can't and make some dumb excuse of why I can't meet her. This isn't even the first time I'm passing something like this up. Happened to me before when a girl asked me if we can make a study group but I said no and made an excuse why I couldn't (although the actual truth was because she's really pretty and then there's me who looks like a potato).

I've always suffered from low self-esteem so I'm used to all this and I've already accepted the fact I will forever remain unattractive but what can I do to make myself more confident so I can actually talk to them without coming off as awkward? and also anyway to decrease my anxiety like shaking, blushing etc? Thank you
