It sounds like you're an ambivert. MBTI forces you into either the introvert or extrovert category by design, even though the trait is a spectrum.
Obligatory reminder that MBTI is pretty much worthless.
Only child syndrome + handicap + need for social acceptance = pretty unique recipe in my experience. I'm wired different than most. I actually quite enjoy it, as so much I learned in private quiet reading time comes in handy. Yes, I know about Punjab. Yes I know about the Falklands. How about Aknor Wat? It really helps to move among the tribes of the world.
