Strange thing is, this doesn't happen with music but only with spoken words.
When there's several conversations at once, brain goes *weeeeee, boom* crash and burn.
The problem seems to be a lot more prominent now than it was when I was younger for some reason, resulting on me having to say "what" or move closer to the person speaking. I can't even remember how I used to deal with it anymore.
Worst case is when a few people are shouting, it burns your ears. (even IF I can handle loud amps, its just whenever someone tries to talk over them, well... may as well give up, I just nod and pretend to know and answer
Because its random and sometimes its very bad or very mild, there's nothing I can really do to lessen its effect and whenever I'm having a bad day or moment with it, I feel so badly out of energy and people say I look like I'm dying, I go pale, eyes go bloodshot and sometimes my damn hands start shaking more than usual.
Its awkward especially when you're out a lot like me.
