I am so sorry. I know this is so hard to deal with. I just lost my mom in May. She had suffered 7 fractured vertebrae last year and was actually starting to improve from that a little when her heart stopped in her sleep. Even though she had been through such a rough year and had no real life outside of the house it was still an shock to. I don't think you can really be prepared for this. I know she just couldn't take anymore and at least she went peacefully. I pray Mark's mother goes that peacefully.

You all are in my thought and prayers.
