Part of it is probably due to the fact that I have been concerned lately that I make others nervous (e.g. that I'm doing something to cause them to become nervous) by the things that I am doing, so I have been trying to modify my own behaviors to curtail this. I am almost becoming angry, as I realize, too, that I am not responsible for other's moods, etc., and, to be honest, I don't think that I am doing anything that should be causing anyone undue nervousness around me. I jokingly said to my mom, who knows all about my anxiety, after returning from a few places, that it's not like I'm planning to shop lift, so I don't understand why salespeople would seem nervous around me.
In fact, I have even heard my mother's voice tremble when she has been talking with me. I feel very comfortable with her, and she knows me very well, so I felt that I could tell her what I was hearing and ask her whether she felt nervous. She was actually surprised when I asked her this, as she doesn't feel nervous around me at all. It's sooo weird...
What do you think might be happening? I also know that when I have consciously calmed myself (even though others ask me all the time how I stay so calm and I seem to be so confident--??

One more thing: I have also been noticing uncontrollable very slight trembling in my own voice when I talk with someone upon occasion. It's hard to explain, but it feels like my heart is beating in my throat. I don't think that it's a panic attack, as I feel more genuinely confident in myself at these times. It's almost like excitement, but it comes across as nervousness to others; as it's happening, I'm screaming in my mind: "Stop it! I'm not nervous! I'm comfortable around this person. Stop trembling."
