Sorry to hear about this TB. She could be depressed. Maybe you could encourage her to go to the Dr. I think that your grandma really misses your mom. It would be really hard to have a child pass on. My mom has been gone almost 20 years, and my grandma talks about her if she has never left. My bf's brother passed when he was 19, and his mom has never gotten over it. I think that he passed in 93. I have read things on this, and they have said some people never get over it. Keep us posted.
