preface: I thought for a long time I was agoraphobic, yet I'm just an Aspie like most of you (I suppose since my headshrinker told me something about it, and I scored 178 and 45 in the tests)
well...what difference do you find-feel between these situations?
1 you are in large place such a supermarket or a shopping centre, full of noisy crowd, you are alone or even with a friend doing your things
2 you are invited for dinner, or in a bar, and there are many people you don't know, but they "interact"
me:
1 no problem, the only one could be the noise but I taught my ears to cut all indesiderable sounds (I'm a musician)
2 many problems, my body and my nerves make me feel like a piece of wood, I try to breathe deeply, I concentrate (and of course I lose what people are talking about meanwhile), I look for a "safe" place, such a distant corner, or just sit where I am, don't move and pretend I'm listening to the nonsense and superficial discussions. I hope no one is going to make me questions, for I just would be so "sincere" to tell them I don't care about their talking and I'm just thinking to my own things, which are more and more interesting.
