OMG, now for probably 2-3 months been feeling similarly. Feel at times can't even hold my head up on my shoulders, speak in monosyllabic format when I'm usually the life of the party, and if necessary can still be but it takes so much out of me, I know I'll be down (as in not functioning, staring at TV, doing laundry, menial labor is all I can actually do, happily I might add, at least I get something done) for days. So basically I stay away from social situations unless forced or I have to carefully schedule them so I have days or 7 or 8 hours in between in order to go to bed, relax, do menial tasks or nothing. I take it personal when I have to be somewhere and only place i actually like going is to therapist. Other than that, can take it or leave it. If you knew me before you'd be like my friends, they think I'm being rude to them or they say extraordinarily stupid things like, "you're so strong, buck up" or something similar, which is now pissing me off royally. Or they say some version of "God will help you"...now that one is even worse, really have they not listened to me for years on that topic. But back to the point, at best I can fire off single words (fabulous, fantastic, perfect for good things; terrible, unbelievable, tragic for bad things) and that seems to work with inflection for most people. Then they don't ask you stupid questions.
