Looking for some advice for 24 yr old who has anxiety and talks to himself constantly.
HELP!!
Sounds a lot like me. My guess would be that this isn't too uncommon. You might want to have him see a psychiatrist if it interferes with his everyday life, though. I think it might be important to find out the reason behind the behavior rather than concentrating on the behavior itself.
I don't really think it's too odd for people to talk to themselves this day and age in certain circumstances, but maybe I'm wrong.
