Freezer Problems

I am just "sick" over what has happened. This morning when I went out to the garage looking for something, I noticed some water running across the floor coming from under the freezer. Then I noticed that the freezer door was ajar. Everything inside was not only thawed, it was warm. The door must have been ajar for days. It is a big upright freezer and was about half full. I guess that we lost about $150-200 worth of food. It could have been a lot worse. A lot of it was frozen veggies and other things that I had gotten on sale, but still. I hate to see all of it go to waste. Ugh!
