Relationship

Geneva
So recently my long term boyfriend left me for my best friend and ever since then every day in school him and her harass me and even tho i have them both blocked they find a way to message me and blame the break up and all the fighting on me. Yet i'm only 14 and i let him use me for sexual pleasure because that's what he wanted and he just made everything my fault and spreads rumors about me and tells everyone my secrets and idk what to do anymore, any help? Also side not i'm already a depressed kid and i want to die already and now i REALLY want to die.
