For me, my main problem when my meds are working is that I constantly misspeak words. I am always calling things by the wrong name or I am unable to recall the name of something I am thinking of. This is not always comfortable since I teach, and kids are quick to correct you.
When I have been completely out of control emotionally, it has been awful. I still continued to be a great teacher, but it took every bit of energy I had to hold it together. Every other part of my life suffered even more.
I prefer mixing up words to being mentally unstable, but I wish I didn't have to deal with either one.
