Sorry to hear what you're going through, it doesn't take much to put life into perspective. My best friend's father has been battling stage four lung cancer for two year and made it much longer than expected, but recently has taken a turn for the worse. He is our duck and goose hunting buddy and it doesn't look like he will make it to see another season.
My Step Mother just got out of ICU and had major heart valve surgery only to find her lungs are nearly fried from smoking, she either stops smoking or falls over dead.
To top it all off another good friend (Owner of my primary hunting property) lost his wife a week and a half ago in a freak SUV accident, the thing popped out of reverse while she was getting the mail and ran her over. I have been spending a lot more time on his front porch trying to be there for him than I have out scouting.
