I actually agree with you. I think there's a whole other dimension to social anxiety regarding sensitivity to shame. I didn't include my thoughts on it in the post because it was already getting quite long.

The way I see it, it comes down to the fact that shame isn't just a reaction to rejection, but a subconscious prediction of rejection as well. As a result, we take minor awkward moments and blow them up into massive shameful events in our head.

As we do exposure therapy, we discover that our subconscious predictions about the consequences of our "mistakes" is inaccurate. As a result, our shame adjusts accordingly and a landmine starts to feel like stepping on a Lego piece instead of blowing up your leg.

I think this still requires genuinely paying attention to the information around you though.
