You don’t say what “social responsibilities” were put on you, but anyone who makes social demands of a grieving family needs to have their head examined. Friends and family should have stepped forward immediately to insulate you from the need to do anything except get yourselves ready for the funeral. When your father dies, you should have no immediate responsibility beyond planning the funeral, and there should already be significant pre-planning done (my funeral is already planned, to the last detail – my survivors have only to hand the instructions to a funeral director.)
Although I hate going to funerals, I do find that the “gathering of the clan,” the ritual and ceremony, and usually the feasting and communion that come afterward makes us cognizant of the importance to us of the person whom we are remembering. The end of a human life should be accompanied by an observance of the preciousness of life and the impact that life had on our own. And, to use the old cliche, it really is good to have a time to say good-bye, a time to get closure. When my grandfather died, it was good to see people I hadn’t seen for many years show up and pay homage to the old man. I personally thanked every one of them I could reach.
Of course, in the case of sudden or untimely death (which is what it sounds like you are describing) the decedent’s loved ones usually are still stunned and emotionally fragile during the funeral. And while people who knew and respected your father should be allowed to pay their respects, their presence shouldn’t ever be allowed to intrude on your own grief.
If what you really wanted to do was go away by yourself and not talk to anyone at all and not attend any kind of service or funeral, your feelings are certainly understandable, but probably not what you really needed, no matter how much you wanted it. Sometimes, what you need the most is the thing you want the least. The pain of attending your father’s funeral wasn’t added to the pain of losing him, it was a necessary and concluding part of that pain.
I’ll conclude by saying that several years ago a woman with whom I had been great friends many years ago (she was my older sister’s best friend) died of cancer. Most of us who knew her didn’t even know she was sick because her husband – one of the most bizarre characters I’ve ever known – didn’t even tell their children about it until she died. Her body was cremated and her ashes sit in an urn in the widower’s living room. There was no funeral, no memorial service, absolutely nothing. Now, this woman, when we were teen-agers together, taught me how to dance so I could take a girl to Homecoming. She gave me tips on how girls wanted to be treated. I was a freshman in high school the year she was a senior, and she helped me avoid the worst of the social landmines of that year. For a time, I had a terrible crush on her, and she knew it, and she handled the situation with grace and humor. She was as much a sister to me as my own Sis. And when she died in pain, tended only by her husband and a hospice nurse, we who knew and loved her never got to say good-bye. I think it was inconsiderate and self-pitying and boorish of her husband to ignore the loss that the rest of us felt.
But that’s just me.
