Do you think she'll be okay?

Stay strong, stay positive. Your great-grandmother must be a very strong woman to live as long as she is. 104, wow, most people dont make it to 100. A person that old to have a small stroke and not to much damage is a miracle, so I have faith she will see her 105th birthday, but remember, death is a part of life. You are blessed to get to know and spend time with her, so keep your chin up, have faith that she will be alright, that's all you can do. I will add your great-grandmother to my prayers.
