Hi Kat
I wouldnt worry about your grandmother too much because she is going to be around for a while yet. Shes not going anywhere soon and she has your grandfather to look after her. Your grandfather is quite capable although he comes across as tired all the time. Hes stronger than you think. Do one of them smoke? I think they have been doing this all their life so they arent going to stop now.
Your Grandmother has given you amazingly great advice over the years and she is very strong. She is also kind and doesnt judge people which is great at that age. She has been your rock because I dont think you got on so well with your own parents or they weren't always around when you needed them. Alot of things your parents left to your grandmother. She is indeed a great lady.
Your Grandfather also needs you as well. He needs you to help with your Grandmother and he needs support if anything should happen to her. Your Grandmother has done what she has needed to do on this earth plane and she has learnt her lessons well. She is a very open woman and is open to the psychic realm and I wouldn't be at all surprised if she isnt a bit psychic herself, although she probably never talks about it. That generation I think.
You will cope better than you think when your Grandmother does pass and there will be support for you as well, although right now you probably cant think of anyone who will support you. Your Grandmother has many great friends that she has known most of her life because she was born in the place she is now. She is well known and she will also have a massively big funeral. Bigger than you could imagine., but this will not be for a while yet, shes a fighter your Grandmother and shes not about to go now because she doesnt want to yet. When your Grandmother doesnt want to do something, well she just wont!
