I am glad you were there and he didn't die alone. I have discovered that all emotional roads eventually lead to alcohol. In retrospect it is now clear to me that alcohol and been corrupting my emotional responses for years. At nearly 12 months it seems to have faded to a point where I think that my heightened emotions, when I have them are real.
I was at the stage a few years ago where I would cry at times when intoxicated and alone. Whilst at the time I would have thought there was a 'reason' for me to do so (eg memories of losses and deaths etc) I now see such episodes as progression of the addiction.
