I was actually just about to post a thread about this!
I don't know if I can relate to EVERYTHING you've just said, but I feel like i'm a pretty emotional T, if that's possible? (it might just be because i'm a girl and was raised in a really emotionally expressive household or because I'm close to F). I do try to look at things objectively a lot though, but I still take a look at my feelings/other's feelings just to get different perspectives on the situation.
When I do break down about something or become overly emotional, i definitely dwell on it for awhile. I've had times when i completely just explode about something and i usually either just completely release the anger/sadness on the person it's about, or i'll write a huge long journal entry about how I feel (yay LiveJournal). Once I do that, i usally feel better, like it's finally off my chest. I won't be completely over it, but it definitely helps. Oh and even though I don't have any time to exercise anymore, I used to feel better about something if i went and worked out while listening to angry music lol.
