This may be independent of typology. I mean, I never mean to represent myself as a spokesperson for a particular type.
In my case, I had my longest hospitalization for depression when I was 29, like over three months. At the verge of it, I'd just discovered typology "forums" or discussion online in 1998, but I was required to go into the hospital anyway. If I'd discovered them earlier, it might have...maybe...just pulled me out of becoming so depressed.
Since that time, I've had many learning experiences and things to overcome, but these may be "me" and not my type. One thing, since the second grade, I've felt compelled to write people notes. Some are good, and some are bad, but for the most part, people don't respond well if you hand them a note.
One summer, two years out of major depression, I was obsessed with some girl, so I wrote her emails up to 10 times per day. I wrote her over 200 emails in that summer. I'd write one, then I send another to fix that one, etc. Fortunately she was a genius and a prolific reader who was able to turn my angst into comedy. She's still a friend today, at least on facebook.
Although it was an amazingly painful unrequited love, I think it allowed me to burn up a lot of my obsessive tendencies.
So thus, my life improves, sometimes painfully...actually usually painfully. It's not like my first hospitalization for depression when I was 17, when I was ripping rubber rooms to shreds and then crying in the fetal position. I don't think it could ever get that bad again.
I guess I'm saying, I'm still growing and improving. If anyone thinks I'm not very mature or evolved, then should have seen me 25 years ago or even two years ago.
