My Personality And Confidence

I'm too shy so I can't often walk up to a girl to just say Hi or something like If I want to make friends with them or just start up a chat. When it comes to romance and trying to become something more with the girl that I like I often get very shy and nervous sometimes not being able to speak clearly and am usually afraid of rejection so I try to not get too friendly because then I will fall for that girl and confess then get shot down (which has happened about four times already with no luck getting a girlfriend whats so ever). My favorite band's drummer and I had a chat about how it was destiny or fate that I would have to talk to him and told me words that would increase my self confidance. Not the best advice but better than what I was given to already. So I kinda hate my personality about being too shy and not just being a bit more confidant in myself.
