I know this is beyond the scope of the thread, but...
I don't think many clinical psychologists or psychiatrists would agree with that statement. If that were true, therapies and medications wouldn't exist. In some cases, being on medication for the rest of your life is exactly what healing means. You're universalizing your own suboptimal experience, which isn't helpful.
It is interesting, though, how many anecdotes from service members who go to "psyc-docs" (and bear with me, I'm using that term to cover multiple disciplines within the various mental health spectrums) and find the method of treatment or supposed reason for diagnosis to not necessarily match reality. I'm NOT saying the docs are intentionally sabotaging the patient, as may be perceived, but instead it seems like a common protocol is to find a base causal factor that aligns with a profession, push that on the patient, and then work from there. In reality, that may not be the case, but allows for an out for the patient if they choose to go down that path, even if it's not actually true.
I was actually having this exact conversation yesterday with someone (military) who goes to a therapist and had that happen to him. I think this discussion has come up in another thread, and at the time, I mentioned I had another sailor that had this happen to him when the reality may have been more chemical than mental (if you'll indulge me in over-simplifying it).
I guess, like anything, it's finding the right solution for the individual, coupled with finding the right professional that jives with the individual's needs. Seems like a universal problem to solve, no matter what the issue may be.
