Fred you are still a young man. When I was 21 I felt that I was indestructible and was here forever. Death never crossed my mind. However in your circumstances having just lost your good friend and losing your child 2 years ago it is normal for you to experience what you are experiencing.
Have just turned 70. I don't think about death much. I feel that as I get older the body is more prepared for death. Don't have the energy that I used to have but I still get out and play golf, do yard work and walk a lot. My father died at 52 and his father died at 46. My mother died at 94 and somebody at her funeral said she died 10 year ago meaning that mentally she was sliding then. So it is a slow process with the exception if a person does not look after himself then it can happen sooner.
Life is a gift. Enjoy your family. We have just one daughter and we enjoy her tremendously. I saw it mentioned the other day. Children are a continuation of us.
The next time I see my daughter I will give her a long hug and say nothing. Tears will come to my eyes because I know my wife and I have been a support for the next generation....
