That is exactly what it’s like for me. For me I find it worse with dissonant sounds. I can be in a loud city without problems because it’s almost white noise I can tune out. But if it’s annoying sounds or a lot of different sounds it’s like a stimulus overload and my brain shuts down and I get irrational and angry.

I finally started recognizing it’s something I do, so I can at least alert someone I’m with that I’m overloaded so give me a moment (preferably away from the stimulus) and I’ll be useless until it passes.
