If you are concerned that you are misdiagnosed, it may be helpful to start mood tracking and symptom tracking. Check out what triggers you.

Back when I was diagnosed over a decade ago, they wouldnt label until they had observed both extremes for a period of time (ie mania for 4 or more days, depression for over 2 weeks although my states last a lot longer than that).

GPs have a lot to answer for in regards to diagnosis, they are NOT qualified to make a severe mental health diagnosis and if your pdoc says BIPOLAR on the first visit - well you've been labeled and they wont see you any other way, and if you have half a brain you know they cannot correctly diagnose bipolar in a 20 minute consult.

Good doctors take a lot longer to label, and some wont even label because of the damage it does.
