Hi siempre nada - I read your 'about me' on your profile and I see you're young. I think it's possible to learn confidence and increase your self esteem. I was very shy as a child and had trouble with confidence. I also found my confidence improves greatly as i got older. Try to expose yourself to various social situations so you can practice. Surround yourself with nice people who aren't judgemental and don't care about the ones who are. Rehearse in your mind before a social gathering and just be yourself.

I often talk about this Iraqi war veteran who was severely burned in a bomb blast. He's severely disfigured, with no hair, no ears and severely stretched skin. Too most people he's very unattractive perhaps even hideous to some. When I saw his interview within minutes, I was oblivious to his disfigurement - his personality was so nice and he had intense charisma. His eyes were beautiful and he had a great smile. He even acted on a famous soap opera. So the moral of this story is, you don't have to be perfect is order to be received well, by the right people. Accent the best things about yourself and just be a nice, person - don't listen to your critical inner voice. Good luck
