It seems like your family consistently mocks and belittles you. That’s no way to show love. I don’t know your specific situation, but I’d recommend finding community outside your family. Maybe find a stutterer support group nearby or an online support group. The National Stutterer Association has chapters all over the country and there’s a great one on Discord too. And prioritize your friends and family who do support you. Focus on your own goals and passions. Living with a stutter is hard enough without people who are supposed to love you making you feel bad about it. Your feelings about your family are valid and you do not have to accept it or put up with it because they’re your family. You do not owe them your time and love if they disrespect and mistreat you. Personally, I give 0% of my time to people who don’t support my stutter and have even gone no contact with family who made fun of my stutter and I don’t regret it one bit.
