I'm seeing a lot of agreement in this thread, though. Healthy, deep relationships with family and close friends are important to keep you grounded, and therapy can help everyone. Many seemingly desirable positions of status that men and women strive for involve incredible amounts of stress, and people naturally have differing levels of stress tolerance, so at some point self-knowledge becomes very valuable. Having good people around you is a great way to build that self-knowledge.
Some people really seem to want men to be very emotional and assume something is wrong if they don't appear to be showing strong emotions. Often, they're just fine, and there's no there there.
If you keep picking at them, you'll probably generate some emotions, however.
I'd compare it to a tooth abscess. It's not like it's so painful you need to scream. It's just kind of there, occasionally causing problems. But if it goes untreated long enough, the bacteria in it can kill you. There are some parallels there with loneliness, which a lot of men suffer from.
So I'd say this is more the realization that "Oh, this pain is because of this source. I'm gonna go deal with that source." The process of dealing might involve making your emotions known (such as when breaking up).
Of course, if you're legitimately not in any kind of pain, then great. But most people are, in one form or another.
This is new to me. Making other people responsible for my emotional well-being is being dependent on other people for our own happiness. Stoicism does not suggest that you do this, on the contrary.
"Handling your own problems" a lot of the time means "making other people responsible for my emotional well being."
I do love stoicism though and I think meditation and stoicism are excellent paths to understanding yourself and managing your internal state.
