I am very sorry to hear about this. What is important to remember is that our loved ones are in a place where they need not worry about anything ever again. Including fears, sickness, and injuries. They are in a place of eternal peace and that is the most important aspect of the situation no matter how the rest of us are affected.
I love you and know he is with you in another way and form.
Keep your head up as he would want you to be strong.
Love you so much!
