I know how you feel brother, back when I was a squeeker I also got pissed that people would judge me for my voice. But now that I am older (20) I understand why people make fun of squeekers. Its because a good portion of them (I would say 75%) are annoying as fuck. You will just have to bare with it man until you hit puberty. The best way to deal with it is just dont talk unless someone wants to talk to you.
