As an INTx, I've wondered if any others have the burden of social confusion when it comes to interacting past the small talk threshold; especially INTJs. Usually, after enduring a few minutes bantering lightly with others, the conversation ceases when excitement arises and I become the inferior associate of the group. I'm not so sure if this applies universally to most INTxs, but it's as if I cannot drop my serious persona; I'm constantly constructing and re-evaluating my words before I speak, and my mind can't comprehend the pace that others normally speak at.
That doesn't piece well with my social anxiety either; SA leaves me excessively sweating, reducing the efficiency and fluency of language, handicapping my mind and builds an acute paranoia. Having both SA and little expertise in socializing also seems to bring out my Fi and Se more, and tampers my assertiveness (I'm vastly passive when crippled by SA).
Anyway, I assume my point has been made.
Are there any other INTxs (INTJs in particular) that have a similar problem to me? Experiences? Solutions?
