I think I do it because I am so afraid of that unpleasant situation happening-because I will not be able to cope as well as NT's. So my worrying starts escalating several steps earlier than it probably should. It has stressed me-working an ER, but has probably saved me in many situations as well. I wonder if it is the same mental process like keeping lists of things or getting very deep in to the details of a subject of interest. We do that process here and end up catastrophizing? (I'm new to this so I hope I'm not reinventing the wheel. I recently suggested to someone to twirl a coin in their finger like I have done--then googled it. oops)
