advice on how to cope with being made fun of?

advice on how to cope with being made fun of? for context i am in middle school. i have been stuttering ever since i was little. idk why but my stutter always seems to be horrible at school. i hate it when my friends mock me when i stutter or when they make jokes about how bad i am at speaking or just laughing at me. i hate speaking because of how horrible i feel when i stutter and because i dont want to get made fun of. i just wish i could speak normally. any advice?
