Yes, sometimes its difficult to find words to express what is happening to me, especially during an episode. When I'm paranoid I say very little because I don't want to think in words, which I believe can be extracted from my head. If the truth be told, my head probably doesn't have much in the way of words anyway.
When I am well (like now) it is easier for me to interact with others, and be reasonably articulate.
My somewhat awkward social skills are another matter.
