Hi Beth. I've never heard of that med either, but perhaps it could be helpful. As for your possible symptoms, I see some as leaning depressive. Not all depressive symptoms seem "classic", though. What I've noted is distress with some obsessive compulsive features. That doesn't mean I think you have OCD. Obsessive compulsive symptoms can often be part of bipolar depression or hypo/mania. See The Link Between OCD and Bipolar Disorder

I've definitely experienced obsessive-compulsive symptoms in the past without OCD. It's a little discussed topic in bipolar disorder. I see clear parallels between your current over focus on Mary and a past one I had with my last psychiatrist. This all follows your distressing experience with the psychiatrist.
