Start a clan, Squeakers United all squeakers can gather and not be hated on because everyone is the same, but you would have to put an age cap on it like 17-18 years old lol
Let them hate dude with time they'll stop you just got to find the right people to hang out with I'm older and people still say I sound like a squeaker mainly out of frustration though
Just be yourself man. You'll regret it if you do it any other way. I used to be a squeaker, but then my balls dropped and I wrecked scrubs. Soon you'll do the same.
