Has SA Made You Jittery/Jumpy?

I've noticed lately that when my SA is really at a high, I become very jumpy. If someone approaches me, especially rapidly, and I am not prepared (kind of by surprise) it takes all I can muster to keep from jumping out of my skin. Sometimes I really do jump noticeably. Anyone else experience this?

I get highly jumpy when my anxiety is high. I imagine it would be a common thing.

When I was younger and my anxiety level was very low, I used to work with this woman who would just about jump out of her skin if anyone so much as spoke her name. I couldn't understand it then but now I think I do.

I think possibly, mild autism, makes me kinda hyper/manic sometimes.
