Hi, I remember feeling nervous the first time I start a thread. I was anxious and scared that no one would reply, but over time, as I made more threads, the anxiety lessened.
I think it's possible to have SA with ADD. I think there are some members on this forum who have both. I'm not taking meds either to battle my SA and other demons, but I think I'm progressing, baby steps. SA could develop into agoraphobia, like in my case, I was so scared of people I barely go out. I hear exposure therapy works for some people.
