Went to the headologist today, and we've added lithium to my cocktail after all.
Apparently what I've been experiencing is called "breakthrough mania." Lithium is the best anti-manic out there, so I'm on a very low dose now, as well as on my other drugs, to see if it helps. I can tell you that I was making my way through the stages today, and thinking things have gotta change. They just have to.
Let's ALL cross our fingers that this helps.
