I feel your pain...as I'm going through the same thing right now. It's so hard to talk to people outside of small "yes, no, yeah, mhmm, cool" answers. I can have scattered thoughts but not be able to get them into words, it's like it just won't happen. I used to have conversations with people about all sorts of topics and engaged in intellectual debate too. I miss it a lot. I wish I had some way I could help, but I'm in the same boat with no answers.
