Bill, very sorry to hear this.
Sometimes words can not describe on how you feel. Having lost both my parents. I have an idea on how you are feeling. Remember all the good times you had with him. Forget all the bad. That's how you want to remember him. You was there for him at the end. That's all of what counts. You did what you could. You maybe thinking that you could have done more. That is what hurts.
We are all here for you.
