My mum makes fun of stutter

My mum makes fun of stutter I don't have a very good relationship with my mother, most of the time we're arguing and shouting at each other. And during every single argument, the only point she'll make is "wwhhat? hahahaha only if you could stop stuttering"(english is not my first language); she's been doing this ever since I was 8, when i started stuttering, I'm 18 now. Every single time when I ask her not to do it, she says "don't talk to me then". Like what is she even trying to say? "I'll make fun of you or don't talk to me". I've been very sad about this for a very long time. Thankfully, I'll be leaving for med school in may 2026. And I don't wish to see her ever again. Thanks
