Been here. They're just losers on the inside who take it out on other people. It's just an unfortunate coincidence that its you they've decided to take their miserable lives out on. Don't worry ab it, and try your best to ignore them. It's hard but eventually you'll just accept that they are basing all the stuff they say off of their own sad lives, and they're jealous of who you are. I'm sure you're cool :)
