Autoimmune/gentle workout trainers or classes?

I am recovering from years of long COVID (I don’t want any shit that it’s not real - I’ve been diagnosed from a biopsy with nerve damage in my limbs) and have been in PT on and off for about 3 years.

I really want to start getting back into shape and am running out of PT covered by insurance. The challenge is that overdoing can be severely damaging (like, can’t do my job damaging) so I need something extremely gentle to ease back in. I can walk, stretch, do light weights, yin yoga etc. I’d swim but I’m prone to swimmers ear.

Are there any trainers or classes tailored to this kind of thing? I live in south Austin and work in east Austin so preferably one of those neighborhoods. I’ve had Pilates recommended. Yin is great but the place I go to only does it once a week.
