So sorry you lost your sister. Of all the sucky things in life, losing loved ones is the suckiest.
I lost my brother years ago. He was obese and in terrible shape, and when we were kids we fought like cats and dogs. But we were close and got closer as we got older. I cried like a baby giving his eulogy. It was not pretty.
All I have now are memories, but I treasure them.
