I'll venture an example just to get this thread going as I'm also curious being newly diagnosed.

One example is feeling good and optimistic or high energy (incredibly high energy) and even creative, however simultaneously having this feeling that I'm just ridiculous and can't actually be any good or any use with my things.

There are other examples, probably better ones, but that's just what comes to mind now.

Ok, wait, maybe excessive irritability and anger, but self hate at the same time. That's a more serious mixed state, especially one of my most troubling ones, but relative to others' experiences, I am probably still considered within the hypomanic range, just for further picture painting.
