I would talk to a psych about it... but it sounds like you surely have social anxiety as well as some body issues. Your psych must have at least recognized that you have anxiety issues if he gave you Klonopin.
I have known a lot of good looking people who thought they were ugly over the hears - I mean, if a cute guy wanted to go on a date with you and then even called you back after you left he must have thought you were cute too right?
