How to give my friend revenge and a lesson ! plz help i lost all my friends and life ! im complicated :'(?

Don't kill your self. thats the last thing u wana do. 1st cry all of the pain away. i was in the same position and in the end you just realise that is was a waste of time. just try to egnore everything that they say at school. put up with it for a bit. then soon they will get bord and move onto some on els. i know how you feel. like you just want to run away!(but don't)
