This definitely affects me, but not all the time (although I think I avoid a lot of situations like this, so maybe that's why it doesn't seem like such a problem at the moment?).

Recently I went to the pub with a group of people I know, but they aren't close friends. Only one of them knows about my head problems and they only know a little bit.

There were two other big tables, it's normally dead silent but it was loud and busy and I was getting really frustrated trying to filter so I could hear what my friends were saying.

At one point I asked a question and 3 people started answering it, I freaked out a bit and think I raised my voice louder than is appropriate to say something like 'I can't do that, can just one person speak!'
I felt really embarrassed when I thought about it later
