NOW WHAT
You showed great love to your wife all the way through. It must be an odd feeling having such a large weight and responsibility removed from your life. I am grateful for your dedication you showed her, always making sure she was taken care of to the best of your ability. She knows all the help you did for her and she's relieved to have the pain finally gone for good. It's a new chapter of your life, but take your time, don't rush into anything. It's right to grieve for a time, to settle this massive change. Remember the good times, forget the bad.
May she rest in peace. Condolences to you and to your entire family.
