I am sorry you are having a difficult time right now. As others have said you are not alone. I too have been dealing with mixed episodes the last while. Singing one minute and crying the next. Talking normally one minute and stumbling for words the next.

One thing I do is to attend to my breathing as my mood swings one way or another. I try to focus on my breathing because often times I am either starting to hyperventilate or it becomes so shallow it is almost like I am not breathing at all. I think the other gift of breath is its ability to keep us in the moment and minimize the effects. Like CesarioRose said, learning to sit with it and not let the emotions own you.

I hope things settle for you soon. Meanwhile breath and remember we are here for you and we know how difficult it can be to cope.
