Sorry for your loss Wayne, your father was obviously a large part of your life and has left a massive Dad sized hole in your life. The price you pay for having someone that special in your life is the pain you feel when they leave. I can assure you the pain will fade and the memories you made together will fill the void. There will be days when you feel the loss more than others and you may wonder if you will ever get over the loss, you will but the only healer in this case is time.
I can identify with you, I lost my Father a few years ago and can see in your post the same feelings I had. I and am here if you need to talk, drop me a PM if you want to talk about it...
