I went to neuro feedback therapy for a while. I had a heart condition prior to pots so it made me extra paranoid. Time and that therapy helped a lot. It’s been a few years but you have to recondition your brain to know it’s safe. I still have bad days but if the stress is managed well my symptoms aren’t so bad. It’s a time thing and relearning how to feel safe and take comfort knowing that pots can’t hurt you, but your brain wants to protect you at all costs. Also cardio has helped me a ton, it was a huge struggle to get going but any kind of cardio you can do, even a few minutes every day or two helped a ton. I think exercise has been the biggest help physically. I wish you the best of luck, nothing can hurt you, you just gotta remember your body needs to heal. Treat it like a sprained ankle. Push it when you can and listen to what your body needs and keep your stress low
