My wife and I had our son's wake on our wedding anniversary.
May God provide you some measure of comfort as you come to grips with your loss. If there is anything I can do to help you work through this, you need only ask, though I don't claim to have all the answers.
Cast your focus on your own family. Determine what their needs are and do your best to help see them through. It will help you take your mind off your own awful suffering.
I lost my Mom when she was 62 and then my Dad at age 85.
It doesn't matter of they are young or well seasoned it still hurts just as bad.
My prayers for the comforting of your heart.
