My therapist has a couple of times tried to suggest things like chair exercises and guided meditations in person.i won’t do them- the chair exercises as it seems like a performance, and the guided meditations because I can do them on my own when I’m not paying by the minute. But I have found yoga amazingly helpful- I wonder would something like yoga or guided meditations appeal to you at all? You could try both of them online, or do classes for beginners.

I think your feelings are really understandable - I relate a lot. For me as well, as someone who suffered a lot of trauma at the hands of doctors as a small child, I am extremely resistant to my therapist telling me what to do with my body, even for the sake of a presumably helpful exercise.
