Spooky,
I’m so very sorry and my heart is with you. I lost my Father (bone cancer) and Mother-in-Law (Parkinson’s disease) some years ago and both were cared for by Hospice. It’s a heart wrenching experience.
I guess if there is any advice I can give you, I would suggest you try your best to distract him from his pain. Hold his hand and talk about happier times. Laugh at a funny story, a parent takes great joy in a child’s happiness.
If he is conscious, ask him if there is business he is concerned about, bills to pay, appointments to set, etc. I realize these things are meaningless to you right now, but he may be stressing over the small stuff. Tell him not to worry and that you are on top of things. Assure him that you are taking care of your Mum and will always be there for her. Give him peace of mind.
If you felt he has ever wronged you and it made you angry, talk about it and let him know that you’ve forgiven him and understand why he did what he did. Talk about how much you’ve admired his strength over the years and how you’ve learned by his example to become a strong adult. Thank him for all he’s done for the family and above all, tell him how very much you love him.
I truly hope his pain subsides and he passes peacefully. You and your family are in my prayers. God bless you all.
Sincerely,
Penny
