robx is right...life is too short to waste, however....losing a marriage is like suffering a death of a loved one. It's tough stuff, and you will grieve. Just don't let the grief overcome you and lead you to dark places. You've been strong enough to overcome drinking, and you can overcome this as well. I definitely agree with robx that you should "get out there and do something that says 'thank you' to you and God for having this life to live."

Hang in there, and buy your dog a different brand of food. ; )
