Does it make sense to do a M.S in accounting and prerequisites for physical therapy?

I don’t understand how the logistics would work. You may be setting yourself for unsatisfactory outcomes in both fields.
Have you seen the APTA website?

Also, if it’s interactions with boss and customers tripping you up, I recommend addressing that at career center and or with a coach or therapist.
Or check out Toastmasters or community service.
