I think I'm finally getting close to determining my type. I believe I'm either an ISTJ or a repressed INFP.
I read that a good way to determine your type is to think of how you behaved as a child, since according to the theory your type never changes, and you should learn how to use your dominant function first. Before adolescence, I behaved very much like an Fi dom. Ever since I was abused, I've behaved like a Te aux. Everyone tells me they see Ne in me, so that's either inferior or aux. I don't contemplate the definition of a turd every time I take a shit, so I'm probably not Ni dom. I'm pretty certain that I'm Fi, not Fe, so that rules out the Ti dom types.
