I have so much trouble with people who I think are higher than me like bosses or the alike. I feel you on caring so much. Most people don't care about our stutters but we become so insecure over the years of embarrassing moments. I'm still figuring out how to cope with it. My anxiety has snowballed over the years. Like last week, my team at work went around the table and talked about what they were working on. I used to be able to do this a couple years ago but last week I had to decline because it's just too much out of my comfort zone. I'm pretty fluent around people i'm comfortable with because i'm naturally out going but I really struggle with strangers, speaking in front of groups of people, or when I'm put on the spot. You're not the only one, my friend.
