I know my T believes the the things I tell him, even when I am emotionally disconnected from what I am saying...which used to be often, and unfortunately, isn't the case so much anymore. (I could stand a little more emotional disconnect and quite a bit less dissociation right now).

Sometimes he has said things that have made me wonder if he believes me, and I have come out, right then, and just asked him. Logically, I think, I'm sure T knows I wouldn't pay good money to come in here and make crap up. Duh! But I was told a LOT growing up, "if you tell, no one will believe you anyhow", so I do have to fight against that fear.

Just like everything else in therapy, I think this is something you could bring up with T. It takes a lot of time to REALLY trust, but in the meantime, some reassurance wouldn't hurt
