So, saw my therapist today, talked about the fuckery over the last week.
He told me that, unfortunately, "Mixed Phase" is a very real thing and it's generally considered one of the most dangerous phases a Bipolar patient can have, because when the deep hopelessness and self-hatred of the depressive phase and the high-energy impulsiveness of the manic phase combine, that's when the most self harm or suicide cases happen. That in fact the last time I had a close call was probably due to a Mixed Phase as well.
Joy.
On the same note, though he wished it wasn't due to previous bad experiences, he was pleased with me for having the self-awareness to recognize that having unfettered access to medications while undergoing this was a bad idea and act accordingly. And that he hopes I don't have any squish accidents this week so that I can have some time to recover all the energy I burned through.
