Actually, you're right. I tend to intentionally act melodramatic, and if it's not for humor, I do it to intentionally to create some other effect. At the same time, though, I think I can get kind of caught up in it sometimes. And occasionally I'll reveal a bit more about myself than I am comfortable with for that situation. As Apollonian said, I also tend to use Ni+Te to verbalize it, although I never really previously viewed it as such. I thought I had a relatively good emotional aptitude, as I find myself able to word my feeling relatively well, and I tend to not go easy on myself, and I tend to push myself to dive somewhat deeply into it. Though to be honest, all my expressions of emotions tend not to sound very "feely", though I find they tend to be quite apt. People tend to understand my "situation", when I happen to verbalize it (which I can be somewhat liberal about sometimes, due to desire to vent), and as philonightmare said, I think most take it seriously. I tend to aim more towards absurdism and a slightly more "intellectually whimsical" attitude, in that I get more relaxed (or possibly stressed) and allow my barriers to slip.
I tend to be comfortable with some level of barrier slippage, but only as long as it suits me. As soon as people start expecting to understand me better or something, I begin to wish I hadn't allowed them glimpses inside my internal state. Too much of a commitment to uphold, I'm not comfortable with such expectations being placed on me.
I also find Fi to be a pretty strong undercurrent. It and Ni tend to act as my philosophical compass. Te is sort of my reality check to see if I'm maybe deluding myself to external reality, but Fi guides my "values" and my views on some ethical topics. Occasionally the basis of my views on things can seem kind of irrational/unreasoned, and I'm not always so comfortable with this.
