When I get really really down like that I do something completely and utterly cheesy....I go out and perform a random act of kindness...I once put some gas in someone's car who I noticed was paying with change...Bought a dessert for a kid at a restaurant...I don't know why it works, but it puts things right back into perpective...you will also find you breathe a little easier. I hope that helps a little! SMILE!! Hey, and I have the same scar on my chest...Makes me feel like a superhero!!
