DO I have an inferiority complex?!

im 20 (male) and im not fat, not ugly, not all that awkward (although i am a bit shy) but it just seems like i dont see myself as much of a ........"person" i guess i should say, as other guys. like when i see a guy whos really good at getting girls, i feel like im a completely different creature ya know, like i could never even come close to getting girls that cute and nice. I didnt have abusive parents, but i was picked on by kids in school. To be honest i dont remember one person in school ever making me feel secure about myself, it was always just endless insecurities, and when it comes to a situation where one person HAS to get the butt end of a deal (or something like that) ill worry about everyone else before myself. It might have to do with the fact that my first and only GF lied to me, cheated on me, used me, and rejected most of my intimacy towards her after the first few months. She told me she cheated on me when we broke up, she was saying it like i deserved it for not being good enough in bed ( i was a virgin, she had 7-8 guys under her belt) (ik it sounds pathetic but im just trying to give all the facts. So do i have a problem, because i dont think that i can do therapy. Writing all this stuff online to wait for face-less answers, is ALOT different than telling someone you dont know FACE TO FACE
