It maybe does help to know that while we may have been more conflicted by grief than some, we've been less conflicted than others.
When we think of 'grief' it can be that we lose sight of the anger we feel at those we love being robbed of their lives by premature death, and our anger at being robbed of the chance to grow old(er) with those we love.
I'm inclining to the view that death makes no sense unless we have belief in the possibility of an afterlife, particularly as it seems to me that anything less makes us subject to random chance, a roll of the dice,subject to the lottery of the alleged grim reaper.
One thing's for sure - we don't take much account of death until we are hit with the reality of it. Or should that be the 'mortality' of it?
I've had to reach an accomodation with death to allow me to continue in life after those I've loved, always have loved and always will love. are no longer accessible to me in the here and now but, conversely, they are in some way more available - I can talk to them as I've always done, and 'see' them anytime and they are no less 'here' and no less 'real' to me than they've always been.
It's taken me a very long time to get my brain around this concept, and I'm not entirely convinced that I've 'got it' yet. but I hope that 'the shortest life is as a long as the longest life' will come to have the same resonance for you that it has for me.
This time of year really is the Dickens - 'it was the best of times, it was the worst of times' and we keep Christmas for the children, and for the child in us and for the child in those we've loved and been parted from through no fault of ours or theirs.
Here's to them
and here's to us
because nothing can part us from those we love and those who love us.
