Sam, If you respond back, do something very simple like "thanks" and leave it at that. You've already had a brief discussion w/her about her feelings, etc., about your family and grandmother. There is no need to rehash it. She's feeling guilty and wants you to make her feel better. This is not the situation in which to make her feel better. You've got enough on your plate.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
