Rog, I lost my father in June. I spent the last 72 hours by his side. Even when I couldn't keep my eyes open any longer I would pull the hospital bed he was in close to the couch I was sleeping on to be close to him.
Although dad and I had many years together doing things we loved and some we didn't I would not trade one miniute of that last 72 hours for any of the others.
We settled every little thing that we had kept buried in our relationship, and I became so much stronger knowing he was fully ready to go, his making me understand helped.
His last spoken words made my sister and I laugh. We laugh about it every time we talk about him today.
I feel your fear, for a lack of a better term. Take what time you have left together and treasure it forever in your heart.
I still have those flashes that make me remember things we shared. His Sept birthday was the worst.
