I'm sorry for the loss you will experience with your mom gone. Seems like she was a very strong woman to have gone through all of that, even with illnesses-and lived to be such a great age. She must have had a lot of gumption. Must be where you get it.
Take care of yourself, enjoy your happy memories, and don't dwell on the sad ones. She had a long life and people who loved her. What a success!
