I get very similar symptoms when I'm experiencing dysphoric/mixed mania. When mixed, I feel very depressed, paranoid, and get racing thoughts. Are you having a hard time sleeping too? That's also a big sign. Mixed mania for me usually does follow a hypomanic or manic episode too.

For me, an increase in Seroquel helped with the paranoia/psychosis. Maybe your pdoc will change your AP if Seroquel isn't doing enough for you, but of course only he/she would be able to come up with a plan regarding medication changes that could help you. Occasionally with the onset of an episode, my pdoc will add a medication temporarily, but once things calm down, I'll go off of the add-on (as recommended by my pdoc). Although there's different opinions by doctors about whether 2 AP's can help, I was on two at the same time, and it was effective at treating an acute episode. I really hope you find relief soon and get the help you need.
