Being the guy in the hospital bed, you gain a unique perspective. A little over two years ago, I was that guy.
Recently, my brother-in-law was that guy. He had a heart attack, got a stent and is doing fine. We talked about "being in the bed" when I saw him last weekend. We both had the same reaction.
When you're in the bed it's your reality. You're not wondering, just feeling. It's your friends, family and loved ones that are in emotional trauma because they don't know what to think. Fear of the unkown.
I hope you are never "in the bed" but if you are visiting someone who is, just hug them, support them, tell them how you feel and know that they are in their reality. It's okay...It's just different from their reality before they got there.
