It must get pretty frustrating and confusing. I'm really glad you have a therapist to talk to about it. And I'm glad you talk to us too.
Are you on meds now, or is that what you are seeing the psychiatrist about?
How about bringing a list of all those troubling symptoms with you? Like the difficulty concentrating in class, etc. And the changing mood states? It might help the doc if you could think about how often that happens and how long it lasts. Maybe even write it down? Maybe your psychologist could help you with this?
I think I've had too much coffee....I can't stop typing! Maybe I'd better tell MY psychiatrist!
