Once you can find the beauty inside your self you will set free all them self conscience thoughts. From what I read you sound like a honest person girls like that in guys. They like to se confidence also, try to think more on the level that they are lucky to meet you. Maybe that will help approach woman more confidently.
Any how most of the super beautiful girls are most liikly to cheat or be bitches. Maybe the girls you think are friends are more your type and you can be yourself more.
I hope this helps.
