Mood Swings or Mental Health Issue? Help!

The dreaded question we ladies are asked too frequently, am I right? But seriously, this post is not about sexism. ha. I'm seeking advice. About a year ago I was diagnosed with depression but my doctors weren't totally convinced, neither was I. I had first noticed some issues about 3 or 4 years ago but things have increasingly worsened over time. Within the last six weeks or so, I've done some research on Bipolar II Disorder and totally, completely resonated with the symptoms/behaviors associated with it. Because of this, I have scheduled an apppointment with a therapist hoping to receive some information about this emotional "instability". The reason for this post is to ask you, Evies, if Bipolar Disorder is ever misdiagnosed as a hormonal imbalance (or vis versa!)? And what are some important things to consider when trying to distinguish between the two?

Much love and thanks <3
