I think you're wrong.

It's possible to make people feel drunk when they haven't had alcohol if they perceive they have had it. What stops a person from feeling energetic if they feel like they have whatever it is.

It's possible to hypnotize people if they believe in it. (It doesn't work if you don't believe it can happen.) There is a lot the human mind can do in particular circumstances.

A lot of people who get mixed states often feel agitated and 'aggressive'. It's like being depressed but having energy to act out on the thoughts running through your mind. It's reported to be the most dangerous because people who feel suicidal have the energy to go through with it. Mixed episodes can be medicine induced too. Sometimes the medication does a really good job of ridding you of most mania, but not depression effectively, so that's why they prescribe multiple things.

I think at most you may come out of the appointment with something for short-hand maintenance that can help even you out, but I don't think you'll get a BP diagnosis. You should tell the pdoc you've looked into BP/Depression/Anxiety so they know you're informed. Try to describe how you feel as accurately as possible, but don't put a diagnosis/diagnosis state to it when you describe it. (This will change the doctors perspective, believe it or not) The doctor may see something we don't see.
