Given all the info you gave above, I'd say you're in a mixed state. I always get most irritable during them. The difference for me, between manic irritability and mixed state irritability is that when I'm manic it is "innocent"-just because someone has dared to invade the personal universe I'm creating. In a mixed state, I go for the jugular and get satisfaction from shutting people up into shocked silence.

BTW, my anger issues are completely gone since abilify. The irritabily is far less pronounced, and manageable when it rears it's ugly head.
