Thank you all for your kindness.
Mom passed peacefully yesterday, having not woken up since Monday. We know that she is happy again, can only imagine the reunion she is having with loved ones who have gone on before her.
Tom, his brother and sister are meeting with the funeral director today. Due to the New Year's holiday, it looks like services will not be until Monday and Tuesday of next week. I wish it were sooner, but it will all work out.
