Welcome to PC. I struggle with mixed episodes. They are very scary. Sometimes I also get rapid cycling, where the moods cycle rapidly between mania, hypomania, to depressed mood. When mixed, I get both the manic and depressive symptoms together, but the episodes are completely void of any euphoric symptoms.

I get complete dysphoric mania, where I am in a very dark place, terrible racing thoughts, insomnia, high energy (but in an agitated way, in contrast to feeling elated), impulsivity that causes me a lot of harm, sometimes a lot of anger, tremendous fear and feeling that the world is coming to an end, delusions, hearing things (especially at night) and sometimes dissociate. It's often the most dangerous state of Bipolar, so please get help quickly. Sorry you're feeling this way. It's terrible experiencing this.
