I also wanted to add that I think it also depends on how sensitive a person is. I am a highly sensitive person and at times this is a blessing, but with my BP it can be a curse.

I can instantly notice those minor shifts in my moods. This is good in some ways because I can use my coping strategies to help prevent it from going deeper. I say it's a curse because at times I wish I had a "break" from it. I'm also highly sensitive to other people's moods and am very good at reading people. Again this can be a curse or a blessing.
