Look through this forum and see how we describe being manic, depressed, hypomanic, mixed and glom on to the ones that seem to fit you.

Most simply, Just being able to present a list of your complaints / issues /behaviors should give the doc a great place to start. You don't have to know what to call it to know you're not sleeping or you're surrounded by idiots so should you laugh or cry? Just talk to him and with his help you both can decide which things seem to fit which categories.

You can always print off the online tests as a place to start.
Good luck
