My misphonia is so bad. Crunching is like blinding red rage for me. Smacking your lips or sucking on your fingers…forget about it. I have to leave the space. I can not manage it within my being. Just attempting to walk away in a rational manner is difficult. I am most likely also neurodivergent but the undiagnosed 70’s kid kind. I just got some of those fancy new earplugs and use noise cancelling headphones a lot. I also have to just get out of there sometimes. It’s so seriously irrational. When I was a lot younger I had a lot of anger problems that I now realize were frustration at certain noises or situations.
