my sz friend never got this. i got it, it sucks, its too painfull inside of me to talk.
It could just be lack of practice.
Being quiet or silent isn’t a bad alternative, though. Difficulty with everyday speech is definitely a brain-related problem. I don’t have any pointers, other than to maybe look into a therapist?
If you’re SZ you qualify for disability, and if you get disability you qualify for Medicare. Many therapists take Medicare as payment and are willing to work with the disabled. Mine is more of a motivational therapist. I think you might need one to help your worth in other things, too, though? Give it a try.
