Christy,
We are in the same place at the same time... my thoughts are with you during this time, it's harder than anything to go through this and to stay strong as you are doing. I know he is happy to be home with you and that you are doing everything to help him be comfortable, feel loved and to maintain his dignity. You're his angel, I hope that you know that your being there probably provides him a great deal of emotional comfort right now. Hold that close to your heart, the knowledge that you have done your best to love him throughout everything that has happened. No regrets
Sandy
