So, the more I think on it, the more likely it seems that I'm bipolar II. The weird thing is that, in being treated for major depressive disorder, I'm possibly being treated for undiagnosed bipolar II. Like, I'm on a mood stabilizer (lithium), an antipsychotic (seroquel), and an antidepressant (effexor). If I were diagnosed with bipolar tomorrow, my meds literally wouldn't change.
