Yes, I know many. Of course everyone has minor mental health problems but I know many who have basically cured mental health problems from depression to crippling OCD. None of them did it purely with counciling but with a vast combination of life experiances, including becoming more prosperous and being able to afford to excercise and enjoy a good diet and not have to worry about losing everything and starving to death (this was a big one for mental health), having children, success giving them self confidence, growing older and having their hormones change, having time seperate them from trauma, drugs, legal and illegal, hooking up with someone who somehow made them feel better, study of human culture, history and psychology to get a new perspective on themselves, and finally finishing their dissertations.

I'm personally acquainted with multiple people who figured out that their mental health symptoms were downstream effects of natural phenomena (diet incompatible with genotype, insufficient sunlight exposure, excessive work stress, etc), with resultant drastic improvement of mental condition after root cause rectification. any reason in particular for you to have asked?

I've successfully addressed several issues with a therapist. I know other men who've also done it. It's about the same as getting a doctor's help with a physical issue--some easily fixed, some taking time and effort, some stubborn that seem to resist all attempts.
