Kat.. Sorry for your loss.. I think all of us here know very well what you're going through. Losing a loved pet is never easy and the resulting meh-attitude toward life shortly afterward is no stranger to any of us...
Good job getting back on track.. Healthy snacks at a baseball game??? I didn't know such things existed!!
It is hard to get back on the horse, but it looks like you're going in the right direction. Keep it up and just let the past week go, as far as the diet is concerned.. Can't dwell on past daliences... The past week was hard enough dealing with the loss of your cat.. Don't worry about what you did, food wise.. This is a new week!!
