I Feel So Guilty

58 hours ago I had my best friend put to sleep. He had a long history of biting and aggressive behavior. I had rescued him from the special needs section of a shelter 3 years ago. He was such a wonderful companion to me. Oh, how he loved me and I loved him. Friday, he bit my 22 month old daughter. I called the vet, and they strongly recommended putting him to sleep. My family has been pushing me to do it for over a year now. They were scared he would hurt my baby. Even though I was so careful when he was with her, I couldn't protect her. The weird thing is that he loved her so much. I think he was just scared of people in general. I'm the only person he was completely comfortable with. But, Friday he scared me. I reacted way too quickly. Within 2 hours of him biting her, he was gone forever. I have been regretting it every minute since. I don't know how to deal with my guilt. I miss him so much. I can't stop crying. He was always there for me. Everywhere I went he followed. He was always by my side. I am sooooooooo lonely. I don't know what to do. I can't stand being in my house. Every where I turn is a reminder of him. Just sitting here at my computer I miss having him in "his" spot next to me on the bed. I have another dog, whom I love dearly, but his personality is so different. Braxton was such an emotional support for me. He loved me unconditionally and trusted me completely, and I had him killed. How do I move on? How do I continue without him? My family is no help. They don't understand why I would miss him. I'm a single mom, and I can't function. Does anyone have any suggestions? I hurt so much. I had thought I was doing the right thing. How could I have made such a terrible mistake? He really was a sweet dog to me and I miss him terribly.
