Well, ignore them. They're not worth space in your brain. I know it's hard, but don't appear to be always tense or depressed, just appear light-hearted with a "f**k you" smirk on your face whenever they say anything mean (but check it in the mirror, people might laugh at it too). Then, just laugh along to whatever they say, tell your own comebacks (don't overthink them), and people will start to ask themselves "what am I doing"? and back off. Also, one thing I have learned is that whenever I say things awkward (and I do a lot), I laugh at myself. This makes it virtually impossible for them to laugh at you when you say something "wrong". Stick with some friends too, if you want to. If it's physical bullying, learn self defense, and tell a teacher or parent, or at least a friend, immediately.
