Could really use some prayers

My grandma turned 86 3 weeks ago, day after her birthday her dog had to be put down, old age, couldn't make it outside or barely walk anymore.
Her cat has been struggling for the past few months. Refusing to eat, not going to the bathroom etc. 4 days after the dog was put to sleep, the cat went missing and my grandma couldn't find her. We went over to her house to look for her and she went and hid in the basement and died

Just yesterday my grandma got very ill out of nowhere and we rushed over to her house and took her to the hospitol. They have been doing tests like crazy but do not have an exact on what is wrong yet.
Please say a prayer for my grandma, I don't think I can handle seeing her go.
