Okay so this ended up meandering over the place. I would like to state that I obviously don't know you at all and this is based on forum presence alone. So a large potential for having the wrong end of the stick.
To be honest I've always found the majority assertion that you are ISFJ at best strange. Which is to say that even if you are; you deviate so far from the standard that the model would be mostly useless. A transgender asexual, OCPD, with what looks like some HSP tendencies. On top of which you seem to be severely depressed. What model could possible predict or account for that incredibly rare combination? Do I think you're an ISFJ? Kind of, I mean depression can have so many crossovers to someone claiming ISFJ e9, that its hard to tell what is the real you. Though if I remember your arguments against Fe did make sense. It's the certainty that people seem to have about your type which is strange to me. The cynic in wonders if it isn't tokenism. The friendly ISFJ to be paraded out, the; “I know a cool ISFJ tadaa!â€
And lastly since I'm here, I might as well add this:
You actually self type as an SEI........ that is from my experience ultra concerning. It's a description of an Russian agrarian manic pixie dream girl. No one in the Western World should be able to identify with it. It's the equivalent of saying; “I'm absolute crap at everything but the most basic adult homebody behaviour, but that's okay because that's all I want/need.†A part of you should want more then that. A little slice of the soul that wants to stab the sun, punch Putin in the face, down some E and run screaming through the streets of London at 3 in the morning. One of the things people tend to forget about depression is that it isn't just black moods, it shrinks perspective. So you can see why it concerns me, the perspective of an SEI is about as limited as you can get.
