I wish I could console you with my written words. Expressions of grief are difficult for me in writing.
How do we do this? I'm a survivor who's experienced the razor's edge of death. My wife was calm, my father not so much. While in that state, I was medicated to the extent that I didn't really think about much. Your dad was perhaps in a similar state. How do you do this? That is a different story.
We are born and we die. That is the essence of life - all life. My focus is to embrace life while I have it. My brush with death convinced me that I need to pay so much attention that I can see the individual grains of sand passing through the hour glass. I slow my life down and focus on my family and those closest to me. My objective of life is to find joy in everything I experience. Find joy with your husband and children and pleasant memories of your father.
