For anyone in this situation and thinking nothing will help, I also had a positive experience with exposure therapy. Around 15 years ago I remember walking to get a pizza and approaching the restaurant getting pins and needles on my back, and drenching myself in sweat from anxiety.
One of my no-gos was going to weight room/area of the gym (I could tolerate cardio area) and one of the first homework activities things my therapist gave me was going to weight room and sitting for 5 mins to do some stretches. It was awful, but within a few months I slowly progressed to the point I was even confident enough to work with a personal trainer.
Slow but consistent incremental exposure to my triggers absolutely made a huge positive impact for me.
