Hey dude, fuck them. Do you. It's gonna be hard and I know you've probably heard these words like a thousand times over, but it's really true - when you stop worrying about what they think about you and start being you, that's gonna be where all the happiness and fulfilment kicks in. It's gonna be tough, but you just need one day or one time where you completely change - for the better if anything, and start being you. But with that said don't do anything dumb - you're probably only gonna make it worse. Keep your head up, get some air and just renew your perceptions.
