You're almost definitely an INTx. I just couldn't tell you which.
I'd guess 5 or 9, due to the odd sense of neutrality.
If you're not an INTx, INFJ or ISTP with a lot of tertiary function.
Subjectively, I'd say you seem a lot like me, except for having enhanced creativity, confidence, and a more sustained analytical drive. And possibly being a bit more oblivious to how things affect you.
What we have in common seems to be a tendency to obsessively analyze subjects we're interested in, curiousity, a desire to articulate clearly, and an odd tendency to sort of "stand apart" from things and look at them from outside. A vague sort of tiredness, irony, and passiveness towards certain things that comes through occasionally.
