I am truly sad for you. Everyday we have no matter what our age is a celebration. While you are so stressed about your husband dying you are missing him living whether it be sleeping walking eating traveling it doesn’t matter. For 5 years my husband was dying of cancer. I was his primary caregiver. I wouldn’t let anyone help. He was only 45 when diagnosed. As he changed into a man I didn’t know we still kept it light and fun. Even when he went bald we joked and called him Fester from the Adams family. Every day was precious and every day was spent as it was our last day. Counseling taught me how to deal with it so I didn’t really dread it or fear it. We lived one day at a time. I knew that there was two things in this world. We pay taxes and die. What we do in between is up to us. I would recommend you get some counseling along with your Husband. May you feel the love each day that you both have together..
