What confuses me about this is that I definitely have mood swings within mood states.

For instance, I'll use depression as an example since I'm currently depressed and I'm certain that I get depressed. I'm also pretty certain I get mixed. I am not certain if I get hypo or manic.

This week I've had a baseline of moderate depression, but at times my mood has swung up or further down due to external triggers being present or removed, some that I am more sensitive to due to being depressed.

Does that happen to people with BP? Mood swings within mood states?

Also: The "yo-yo" thing. Can that not happen in mixed states, if there is switching back and forth from one state to the other? I understand mixed states involve both happening at the same time, but have also read that switching from depressed to hypo/manic can take place in mixed states as well.
