I think Sometimes Psychotic suggestions are right.

I also want to tell you that you have to stop thinking so much about how you sound and just go with the flow and make with the jelly. ~____~ Maybe you are nervous you will sound stupid so you try to limit your interactions...? Speaking doesn't get easier that way.

I am pretty sure I'm dyslexic and I know for a fact that I have can't read body language in groups. I stumble over words and often forget what I'm talking about mid-sentence but it doesn't stop me from interacting with people around me. If I'm corrected, I just brush it off and move on. It is annoying and I wish it didn't happen but I don't have the capacity to worry about it all the time. (Especially if its what I'm dealt with)

*Maybe* you won't sound as eloquent as you did before your psychotic break but it won't get better by ruminating on it. Practice makes perfect. (AKA Think about it as learning how to ride a bike for the first time.)
