The Guilt

I came into Suzies life by fortune almost 4 years ago. Her owner had died and she was going to the pound, I reluctently took her home. It was the best thing that I ever did, she fit in with my other 2 dogs and 3 cats like she had always been here. She was old like her previous owner. I have never loved an animial like I love her. She has had her health problems and has needed up 4 and 5 times a night to potty. Last night she was up my husband was supervising her like we always do, he had to use the bathroom and I did not get up, assuming she would be waiting at the door when he returned. She fell in the pool and was drowned by the time he returned, not even 5 minutes. We tried to get the water out of her lungs and attempted mouth to mouth. She was dead, I let her down, she loved me so much and she trusted me. I let her down... I dont know how to cope, I let her down.... looking for support... need to get thru the day...
