how do you talk to people?

I used to talk to people back in 5th grade until one kid told me to shut up because i was annoying, but I ignored him. then in middle school I was laughed at and picked on to a point where I felt like dying and my voice was the reason so I stopped talking to people openly. then in jr. high and high school I usually talked once in awhile. but now, I haven't been able to talk to people, especially girls and this one girl I have a crush on because I forgot how to I guess, and I'm afraid what others think of me and the way I talk.
