Hubby works nights so he's usually not here when I do need to vent, but I will occasionally call him at work. I'm actually in a good mood the majority of the time even when I feel like crap. When I went through the breast cancer, I pretty much joked my way through it (how much money I'd save on bras, etc.).
I figure that no matter what I'm going through or dealing with, someone else has it worse than I do.
