I don't know what it takes to "be prepared." I knew the day would come as you did Steve, but when it arrived, I was in the same shape you are. As others came, it did not become any easier, just more familiar. The two who were my closest friends were just incredibly tough and in the one case, I knew for almost 5 years that the day was coming.Get some rest my friend and over time you'll begin to assimilate his passing and loss. I am serious about spending some of your time with his family. It will be a help to all of you.
You are in my thoughts and you have my best.
