First, I am so sorry for your loss. It sound like it was a long road for her and I am happy for you that you got to say goodbye when you did and had that closure. I am also glad that you got to go home and be there for your mom.
My Nana recently passed and I was so grateful that I am still only an hour away and could drive down and help. I stayed at my grandparents an entire week, with all my Aunts and Uncles, my Mama, my Brother and several cousins. It took all of us to go through everything, make arrangements, and get everything done, as it was unexpected and she didn't exactly have a plan in place [although she did have savings and life insurance plans to take care of my Pa].
My Mama is usually the one to take care of everything and she and her sisters were all just total messes [they still kinda are]. My oldest cousin, my brother and I did everything for several days while my Uncle and his Wife planned the services. It really did take all of us, and I was so glad that I could be there.
This has really shaken my resolve to move to the UK permanently. I know it's still the right decision for my family, and my husband will never fit in here, but it hurts to think that, if my Mama went into the hospital without warning, I could not get to Columbus, GA in less than 12 hours. My cousins were all very supportive when I shared this concern with them one night, telling me that they envied this opportunity I have to raise my kids in Europe, and they would hold down the fort until I arrived, but I can't help thinking, 'what if I don't make it in time?'
It's just so heart wrenching and horrible to think about. As much as I want to live there and raise my kids there, I feel like I'm denying them some essential part of the human experience that I got: to grow up surrounded by family. To know 1st and 2nd and even 3rd cousins like they are your own brothers and sisters. I know they have all their cousins in the UK, and they are close in age to many of them and my husband [thank god] comes from a fairly close knit family, but it's not exactly the same
