At the He-Man club of course. We all face our challenges with stoicism like Odysseus when his sailors got eaten.
rephrased for ease of interpretation - venting about a problem is nice just as stretching a muscle is nice. stretching doesn't fix the root cause of muscle soreness though, just as venting does nothing to fix the issue. emotionally re-reacting is likely to result in strengthening of existing associations, which is more likely to cause repetition of a problem scenario, as opposed to leading to scenario avoidance.
"talking about your mental health" does not mean re-parroting your trauma. there's understanding, re-framing, forgiving, all kind of other things that go beyond the limited belief that talking just calcifies trauma.
Do you know a single person who has cured their mental health problem?
Yes. What point are you trying to make?
I think that's obvious. He doesn't know anyone who has, and thinks the whole thing is a waste of time.
Yes, me. I suffered some serious depression that I cured through therapy and medication. Discussing it openly with my family and friends certainly helped.
As the saying goes, recognizing that you have a problem is the first step to being able to solve it.
venting is a form of talking about mental health. there are other forms that the problem statement doesn't apply to, like your examples. but the statement does apply to my example, therefore we can't say that talking about mental health is exclusively a positive behaviour.
Can you think of anything you can do that is exclusively a positive behavior? Drinking water in excess kills you, excess breathing kills you, excess exercise kills you, I think the logic here can be used to sow the seeds of uncertainty in nearly anything, honestly.
your argument is like mayonnaise, liberally applicable in many situations, but it's a bit bland and not the condiment I'd choose for this dish
