Samuel,
I just wanted to let you know a story...
My grandmother (who I no longer speak to, due to some personal issues between her, my mother, father, siblings and I) had 3 strokes last April, and on top of that her diabetes spiked, making her blood sugar numbers go into the 600's (and your numbers should never be over 170). Her blood pressure was also very, very high.
Despite all that, she recovered in the hospital, after a few scary moments where we though she might have been in a coma. She never went into one, and about a week later she was out of the hospital, doing fine.
Now she has lost most of the vision in her left eye, and has some balance issues, but she is well enough to be living on her own, without help.
I do know a bit about aneurysms, and they can be very dangerous, so I'm glad your grandma is ok.
