When my dad died I was 18 and had graduated from school and was pioneering, this is what my dad expected of me. When he died he was having an operation and my mother, aunt, and I,( can't remember who else was there), went to eat while it was going on. We came back and were waiting for the doctors report. The doctor walked in and said,"Well, he died on us." It was a shock to us, we never expected it to happen. I remember sitting there for a minute and trying to accept it. I cried a little, got up and got a drink of water and came back to where my mother was. That was all the emotion I showed.
Actually I was relieved that I could now go to work and didn't have to continue pioneering. He didn't have any insurance and I had to work to support my mother and I. I wanted to get married and start my life and I couldn't if I pioneered. About 2 years later I got married and was happy, got all the sex I wanted from my new wife as well as a partner and companion. We were happy. I really didn't miss my dad until later in life. I just thought he was gone for a few years and we would be reunited in the resurrection. This hope did make his death a lot easier.
Now I just accept that death is a part of life and we will have to deal with it the best we can. I don't know how I could deal with the death of my kids though. It would be devastating.
