I had my heart surgery set back a month, and it just crushed me. I had a hole in my heart repaired, and the part that was being put in my heart requires a specialist from the manufacturer be present for the surgery. He had a change in his schedule and could not be there. It felt like the end of the world. I had gone through the mental planning...my family had done the same...we were all set to go. That was six months ago, the surgery was successful, and I work out every day lifting weights, all muscled out...not bad for a 60 year old man. I am fully in your camp. My best advice is to accept that this has happened to you, and it is not the end of the world. Acceptance is the key word. Every day in your life is important. Don't let this worry away your happiness for the next month, or how ever long it will take until your surgery takes place. Your family at home and OUR family here will help you through this.
