Jennifer, so sorry to hear your news. Your mum is at peace now. I'm sorry you couldn't be with her, but you did everything you possibly could to be there for her.
Take care, now. You're going to be all over the place, try not to worry on the journey, everything will get sorted.
Jennifer,
I'm so sorry to hear your sad news and that you were not able to be there. That's one of the tragedies of being across an ocean. At least she went peacefully. Thinking of you.
Love
