Welcome, bide! I'll just second Sapien's suggestion to get referred to a psychiatrist. Only they can diagnose you.

It requires an expert to decide if you have a mental illness or not. Certainly your having been psychotic is something a psychiatrist should know. As is your past psychiatric medications and its history. Did that old doctor actually say you were "psychotic"? You'd want to describe that actual experience to a doctor.

As a side note, if you suspect bipolar disorder, avoid referring to it as "BPD". I'd call it "bipolar disorder". Why I say that is because "BPD" is the abbreviation for "Borderline Personality Disorder" a whole other mental health disorder. I understand the confusion, though. If others have used that abbreviation for bipolar disorder, they were wrong to do so. A better choice is "BP". The medical community may also use "BAD" for "Bipolar Affective Disorder" but that abbreviation sorta looks "bad", so many with the disorder avoid it.
