Hmm. If you know the name of the T you saw as a child, and he/she is still around, he might have basic dx info on file still. (It's a bummer that after 10 years your history is usually "gone" from files.)
I don't think a T would talk about meds just to pass time.

T time doesn't have to be "juicy" stuff... even issues about why others think you're "crazy" can be discussed. Obviously it affects you, T time can help you come to grips with being "different?"
I hope you don't have many sessions where you feel it's a waste of money. There's something going on, or you wouldn't feel the need to go ... I hope you are able to open up sooner than later. It's a trust issue. You need to discuss little things to be sure the T can "handle" your real feelings.
