I’ve been once or twice. This was in my late teens, early twenties when my parents were convinced I was depressed and they put me on antidepressants (which didn’t seem to do anything) and insisted I go see a professional. I don’t recall much about it because it was mostly just introductions and general questions. I think they wanted to know about my worldview and I ended up getting philosophical, which sent the conversation on a tangent about metaphysics and at that point my time was up. I didn’t really get anything from it so I didn’t go back. Regardless, I didn’t think there was any deep trauma in my childhood or teenage past for therapy to help.
Fast forward a decade and what my parents thought was depression I suspect was more along the lines of Adult Onset ADHD which led to a series of depressive episodes, which would explain a lot. Maybe if I’d continued with therapy the therapist could have recognized the underlying cause of my distress being due to very selective ability to concentrate on tasks and they could have done more to help, but I don’t think there was ever any hint that anyone considered this.
In terms of physical therapy, I did have a minor hip injury in college and went to therapy for it quite a few times. That seemed quite effective from what I could tell and I haven’t had issues with it since.
