Freewill, I have asthma (and I'm 56, "got" it 3 years ago after 5 months of working with a systemic infection and too many antibiotics, grrrr) and it's been giving me fits the last couple months, getting better then worse again with the weather I think.

Sorry you're feeling down. I generally find some new books and curl up for a couple days until I get an idea for a new "project".
