I know how it feels being terrified of stuttering in front of someone who may know you, but not that you stutter. I don’t have an answer for any of your questions. Every situation is different, and I am still just learning and trying new things all the time. I have friends and family who sometimes laugh and even make fun of my stutter. One friend in particular used to really go in hard making fun of my stutter. He would imitate my stutter and laugh in front of me. I think he felt like I was open about stuttering, and that I sometimes looked funny, so I wouldn’t be offended by him as a friend. He was an “edgy joke” kind of guy, and I like him for it. A couple years passed with me uncomfortably laughing it off. Eventually I was honest with myself and realized that even though he is my friend, I would prefer if he was a little more sensitive towards me because this topic was painful for me(hard to admit that to myself). I still didn’t do or say anything for a long time. One night, I was having a heartfelt conversation with him about emotions he was struggling with. I hesitated for a moment, and then I started telling him about what it has been like living with a stutter. How humiliating it can be. How terrified I am in normal situations. How I worry about people thinking less of me. How I worry about finding someone to love me despite my stutter. He really listened, and I never mentioned how I felt about him teasing me, but he never made fun of my stutter again after that night. That experience inspired me to have similar conversations with my parents.(it might sound weird to you, but I had previously very rarely spoken to them about my feelings) I can’t say what you should do, but maybe you can learn something from my experience.
