It's a hell of a thing. Yeah, that can do it; sorry you had to go through that one.
What can happen once, can happen again, and someone relies on me, so enter memories and I need to keep myself functional for them, so enter avoidance (no matter how irrational; mental illness be mental illness and one can only fix it so much). It's quite predictable there. Though, the hypersensitivity of autism is physically similar, or even more uncomfortable in my opinion, and I have no need to be around crowds or people, so it works out either way.
I'm sure my now retired psychiatrist would be saying you need to confront such things (comfortably), and he's probably right, but I can do it if I have to, and that's what matters (which he would agree with). It's only an issue if you avoid it and it ends up harming you in some way.
