Hmm....over cleaning maybe, when my mind gets super cluttered or anxious I have to be doing something. I can't stay still. I also look at the floor a lot when around others or anywhere other than looking at their face for long.
Maybe my stutter. I can't control it sometimes. It's quite mild, but it does affect me. I have had it as long as I can remember. SA definately makes it worse, though. I went into a coffee shop a few days ago, and when the lady asked me what I wanted, I couldn't get anything out for about 10 seconds, so I pretended that I was still looking at the menu.
