I am so sorry for the loss of your friend. I as have far too many of us have lost friends to this terrible demon.
My best friend did the same a few years ago, and I am sad to say I was not shocked, as his brother did it many years ago.
The cycle has begun, the fear will be the son will take the same route.
Keep your chin up, be there for him and if you need anything, you call me anytime.
Deepest condolences to family and friends.
