The problem with confidence is that you can't act confident and even if you could pull it off you couldn't do it forever and eventually every person will reveal their true selves. You have to build confidence and self esteem and learn that it isn't connected to what you see in the mirror but to what you have accomplished. Your self image can be built and rejection happens to all of us. When your self image is connected to your accomplishments there is no one that can tear you down. One of the guys I was deployed with lost his arm and he gets *** like you wouldn't believe, some women are freaked out by it but he doesn't let it slow him down. If you have a problem getting women I would suggest you do start on the ones you don't want just to get used to socializing with the opposite sex.
