I'm just curious, does anyone else ever experience show-stopping fear without much in the way of physical anxiety symptoms?

Often cited are: blushing, difficulty breathing, excess sweating, nausea, palpitations, and trembling

In the past I have blushed, or felt nauseous, or had my heart race. So I'm capable of it.

But for years now I just get tense and maybe a bad feeling in the pit of my stomach. That's it physically. But the mental state can be paralyzing. As in, I just cannot do it. So I doubt other people see it, unless I get a deer-caught-in-the-headlights look or can't conceal that I was trying to do whatever it was.

Anyone else?

(I'm not posting this in one of the anxiety disorder forums because I don't think I clinically have that. However I have some serious avoidant issues. Also, I'd just like to cast a wider net, because everyone is scared silly at sometime in their life.)
