Hi Blaire-
I had this problem too and asked about it awhile back. I think it's easier to get advice about what to do in the low periods. I know for me, little positive things set me off kilter, typically sending me up a little before I head back down. Before I was diagnosed I told someone "Oh, I can't handle good news, it just doesn't feel right" I now realize that was just BP symptoms... still working on solutions myself. My current way of doing it is just trying to balance my brain going "Oh this good thing happened!!" and then my brain runs away with itself, I try to measure anything good with "Yes, but there are still challenges" or "This is not that big of a deal" or "There will be these good things and these bad things..." Anyway, basically, I try to make sure that I feel grounded, but I'm curious/very interested to see if other people have better/more developed coping skills. I'm still new-ish to (knowing I have) BP.
