I am so sorry to hear of your grandmother's passing.
It is great that you were able to see her--when my grandfather passed, I hadn't seen him because he told me "I'll be fine, stay at school and study, and I'll see you at Thanksgiving" He passed the Friday before Thanksgiving.

I hope the memories you had with her will be a comfort to you, and my prayers and thoughts are with you and your family during this difficult time.
