Here is a few videos I think you may benefit from. The first one is a breakdown about Bipolar disorder and the diff between type 1 and type 2.
And just so you have a good understanding of psychosis.
Kati's youtube channel has a wealth of information.
I'm curious how many times you have seen your psychiatrist before he diagnosed you, and if you have therapeutic sessions with the pdoc or if they just do meds. Where I go the pdocs do meds only except for the first session where they question your history and symptoms. You could probably benefit from seeing a therapist too, and it would give you two points of view about your diagnosis.
