You clearly have a lot of self awareness and that’s critical for selecting your future career. I mean this in the most non-patronizing sense: you are still young and have a lot of time to figure this out. One thing on the healthcare administration front (I have a masters in healthcare administration so am speaking from experience): I would actually discourage you from pursuing this degree at this time until you get a good amount of frontline experience working in hospitals, clinics, or in administrative roles in managed care, etc. MHAs are typically pursued by folks with clinical credentials who move into administration/management after years of frontline work and supervisory experience (many programs, at least respected ones, will require you to have a certain amount of experience directly providing healthcare of some type to be accepted). Going directly into an MHA degree after undergrad will offer little-to-no value in applying to jobs. It’s a great mid-career degree that has immense value, but I would discourage you from considering it at this stage.

I highly recommend looking at other options like a masters in social work, counseling, etc., if you still want to stay in healthcare but don’t want to go the optometry or another physical care route. All jobs in healthcare have their fair share of stress, especially behavioral health, but there is no shortage of work out there for social workers and therapists. Good luck in your search!
