First I will say sorry you are having a hard time. The world is definitely chaotic and tough to navigate right now. Don't give up and don't let your stutter make you feel like you are trapped. I for have a mild stutter and it's motivating me to be an entrepreneur. Maybe it can motivate you too! As for your mom you should explain to her how it makes feels. Don't allow others even if it's a parent to belittle you. You have every right to defend yourself, if anyone disrespect you. If she doesn't want to acknowledge that she upsets you. Definitely make plans to distance yourself. I think a lot of parents learn boundaries when you set and stick to them. She was totally out of line for doing that.
