Hmmm, I think it's perfectly reasonable for people to say "everyone feels like that", some may be symptoms of ASD, some may just be personality traits that you just need to grin and bear.
I despise people being in my house, and noise like banging goes right through me sometimes as if the banner is hitting my skull. I also may not want to leave because I don't want anyone to talk to me.
AGlass, what you described is also how I would feel in that same situation. If I have an event to go to, wedding, conference, party etc, I wake up every morning in the months before it and the first thing I feel is dread, feel like it's a train coming for me, hurtling towards me and I can't stop it. On the day, in all over the place, can't pick outfits, clock goes too fast. When I'm actually at the wedding (or whatever) I feel so uncomfortable that I'm not really in the moment , but instead I'm just standing, feeling like everyone is judging me (negatively), even though deep down I know it's not about me!
Of someone asks me anything and I'm put on the spot I can't think of the most basic reasons, even things like " tell us about yourself/what are you up to this weekend etc, total mind blank. Then I breast myself up over stood things I've said our didn't say every day for months after it.
But is this ASD or just my personality? If someone with ASD said to me some of the things that have been mentioned here, I'd say "lots of people feel like that".
