Thanks for your update Roy and good to know Misty is still with you, persevering through such horrendous ordeals. I have no doubt that your love for her goes quite some way in her recovery and that of your family. The power of love is not to be underestimated!
I fully understand how the uncertainty of a future concentrates the mind wonderfully and creates a sharper perspective that better highlights what can be appreciated (maybe that was once barely acknowledged);it enables more quality experiences, I find.
I am now 70 and still reap these benefits i.e. the repercussions of having 3 close encounters with death (all accidents) in my 20's!! I have never stopped appreciating being alive i.e. on a daily basis and am continually grateful.
For those prone to becoming embittered by life, I would say that fostering gratitude/counting our blessings is key to offsetting this and enabling life to be tinged with sweetness again. It is possible...there, waiting to be discovered - just requires an open mind and, perhaps, a leap of faith! (Gets off soapbox, ha!)
