One of my best friends in the neighborhood suffers from social anxiety disorder with resultant panic attacks. He can't be in places where he gets surrounded by people and starts to feel like they're all judging him and as a result of that tends to go into full blown panic attacks. He now mostly goes for walks with his wife late at night in order to get some air. We play chess together on occasion and he always tells me how this problem has fucked up his world.
I always tell him to go to a Psychiatrist for some help, but he hates the stigma. I'll tell him about your dietary modifications, that might be a good start and easy enough for him to employ without it being too drastic.

I had that issue for a time too, full blown agoraphobia
Then one day I said fuck this, if i panic i panic, no one is judging me, I just quit caring about the panic,...yup it absolutely sucks but I rode it out, even in public, and it just got less and less over time. But i still live and die that the stomach is the main key
