My sympathy goes out to you, Longtime.

My mother died a year and half ago. Sudden illness. Don't know if the vax exacerbated it (now that I think about it, very, very possible), but it was an extremely difficult and painful time for her. Our greatest effort was to ameliorate her suffering and help her to make the next step.

Passing on is the second greatest step we make in life. I'll say a prayer for you and your parents in this journey. I'm sure many anons here are with you in spirit.
