When my father passed away in 2011, a number of things got me through. The most important was knowing he knew Christ for the last 5 months. I knew he was with Jesus.
My sister came and helped me with the funeral, I busied myself not just planning but writing the funeral. I was taking pastoral ministries, but I also wrote the sermon, although I did not preach it. That is not a good thing to do when you are grieving. My sister did the power point, and I arranged everything else. (My church family also helped tremendously - the church, the ladies helping with the caterers, the comfort from the pastors!)
My husband lost his father in his teens, and he knew all about grieving. He was a real shoulder to cry on. My kids loved my father, and they all came to the funeral, except one who was somewhere playing hockey. Although he went out of his way on the way south, came to Edmonton and spent a few last days with my father, who was in the hospital dying in the fall. We had some great talks about my dad, and the memories the kids had.
My mom didn't want a funeral, but fortunately, my sister got it written into my father's will. It was supposed to be small, and it sort of was! She would only let the death announcement be in the paper for one day. But, various sports teams got a hold of it, the university where he was a professor sent out a notice. And the people that turned up were amazing. There was the junior high basketball team my dad coached to the provincial championship. Everyone alive on that team came, and they had a picture of the team for me. Of course, lots of his colleagues. The Grey Cup was that weekend, but he still had an honour guard of some younger players from his CFL team. There were many more! I guess grieving together was important for me.
It was touching to see the fond memories all these people had of my father. He wasn't just my father, but he had made a big impact in my community and touched lives. And in turn, I made sure the sermon touched hearts and lives, and reflected the changes in my father's life as he had turned to Christ.
It took a long time before I could really sob about the loss. I ran from it, busy with seminary, assignments, etc.
I'm not sure if any of this helps you. Just sharing what helped me in the death of the person I was close to.
