Can someone please explain to me what they've experienced as a "mixed episode"?

The other night I was super agitated and found myself yelling at my bf on the phone. I was getting annoyed because he wasn't listening so I had to repeat myself several times and when I did I yelled it... to the point where he even had to say "geez calm down, I didn't hear you."

When we got off the phone my mind was racing and I felt anxious, but at the same time I felt super depressed. I remember saying, "I don't want to be bipolar anymore" and started crying. I remember thinking it was odd I felt so sad... I've been diagnosed for several years now and normally never get "emotional" about my diagnosis but for some reason that night I was. But like I said at the same time I was hyped up, irritated, and aggressive with my bf on the phone. That's when I thought to myself "am I having a mixed episode?" and looked it up online and found out it typically happens with Bipolar 1 patients (which I am).

Funny thing is, idk if I've ever acted like that before, or if I did, I didn't realize it or recognize it as a "mixed episode". I'm definitely going to start paying more attention from now on.
