Every Day is A Blessing

I have always firmly believed this and that every day is a new mercy. A chance to get it right, with God, friends, family, loved ones, yourself. But then I witnessed illness first hand. I know that everyone thinks sudden deaths are the worst thing that can happen. But for who the mourners or the deceased? I think its the former and the latter is way better off. I know that as a believer I should count it all joy but that's easy to say as a healthy (at least to my knowledge) 26-year-old with food, clothing, and shelter. How do you keep your faith and hope when your old and weary and everything, even going to the kitchen for a glass of water, is a struggle and the pain seems unbearable? Is every blessing that you experienced before the illness worth the burden? Does every sunset, every moment with the ones you love, and every deep belly laugh until your eyes start to tear outweigh the pain? Does old age and wisdom just better prepare you to hold on to God's unchanging hand? What about us young folk who can only watch and try to help and pray and attempt to make sense of it all? I'm at a loss. Well better yet, let's say I know in my head the right answer, the scriptural answer, but I'm having trouble getting my heart to accept it. Maybe you all can help me with this one.
