No, a mixed episode is not an uncommon thing. I have them a lot really. It's the feeling of both mania and depression together. For example, I have racing thoughts, pressured speech, feeling like I'm racing inside, with extreme irritability, can cry at the drop of a hat, and tons of agitation, no concentration, just feels like someone is shaking me really hard on the inside. I feel like this so much I will say I feel "more manic," or "more depressed," because probalby 95% of the time I feel both. It's exhausing.

You should tell your T or pdoc. I would tell mine if I had any.
