I think some of these work up to a point.
I recently talked with my partner about this, and annecdotaly, one friend had bad enough depressive episodes, they got an antidepressants prescription. Later they complained that it really helped with the downs of the depression, but in general it felt stifling and kind of muffled the highs in life previously accessible.
But, fortunately, the medication helped enough that they started and stuck to an exercise regime and then managed to phase out the medication.
I think with mental health in general, everything comes with a great deal of your-mileage-may-vary.
