Every once in a while I have these spells (or episodes or whatever you want to call them) where the disinclination to communicate is so powerful that I'm functionally mute. I can't call for help, I can't tell people I'm OK, I can't tell them I'm not OK. It's like I'm in a state of psychic shock.
Your current state reminds me of these spells, only of much greater duration.
May someone understanding be there for you when you are able to reach out again.
