I think my best friend secretly judges me for my impediment

I think my best friend secretly judges me for my impediment When I stutter, it only really comes out when I’m nervous and or around the group of people. A few days ago, my best friend invited me and some other friends for brunch. At one point during the lunch, one of the girls asked me a question about myself. So I was talking. I can mask my stutter pretty well. But sometimes I speak a bit fast, or my voice becomes squeaky. When I was responding to another girls question, my best friend started twitching her eye at me. It was something she used to do in high school whenever she was annoyed at something. I don’t know. Maybe I’m just taking it to personally. But I just get so nervous and wish I could be like anybody else.
