I really lament to hear that you've also lost your sister mate. No doubt it is a heart breaking experience. In my case it was devastating because it was very premature and totally sudden and unexpected. She suffered a CVA due the rupture of a cerebral aneurysm with the subsequent [SAH](https://en.wikipedia.org/wiki/Subarachnoid_hemorrhage) that kept her unconscious in intensive care for more than twenty days. However, she managed to wake up and began to show signs of recovery without apparent major secondary damages. What obviously gave us increasing hopes that maybe it would not pass of have been just a big scare. But then, no longer she had a second stroke that this time she could not overcome and has passed to a better life. Yeah, I know she is in a better place now and that comforts me a bit. It really grieves me that during 15 long years I didn't have the opportunity to give her a big hug.
