Both of my parents died at home, with children and grand kids with them. Mom in '98, Dad in '03. They were both well up in their years, but both suffered with long term illnesses.
You can always be proud and happy that you were there with Mom when she died. And as hard as it sounds now, hope and pray that you can be there with Dad too when it's his time.
You will both have a tough time grieving, sorrow over your loss, and bitter sweet thoughts about the times you spent together. Remember those. And in case you aren't aware of it now, it'll be OK to smile and laugh when you think of things that Mom caused, or you caused and you all lived through together.
Take care of your Dad. He is going to be going through even more than you will be for the next several (read that as MANY MANY) months. I really believe that men suffer more with the loss of their companions than women do. He will be lost for quite a while. He'll have to relearn how to do a LOT of things you would never think of now. Cooking, washing dishes and clothes, everyday things. He'll call you and cry, telling you that he wanted to say something to Mom and then remembered that she wasn't there.
You're a tough Lady, you've shown that to us over and over. Now is the time for you to REALLY be tough, and be there for your Dad.
God Bless each of you and hold you Safe, now more than ever.
