Oh yeah, I can say things and not remember what I said, and then people get mad at me because I said the wrong thing... that makes sense to me! That's why I like typing... can go back and delete before you show anyone.
As for the t.v., though.... that's a hard one. Have youd discussed with your therapist that you actually talk to the t.v. I think the big question is if you think they are actually talking to you? I think that is the red flag you're looking for, and if that's not the case, it's more a symptom of loneliness. Like... yelling at the coach when your sports team is doing bad is pretty normal, I think. Or like saying "Don't go in that house! He's waiting for you!" during a suspensful part of a show or whatever, that's totally normal. But thinking your favorite sitcom characters are actually talking to you is more something to talk about with the therapist.
