As Lara said, your mom was so young & suffered so much. You too, as her son. I am glad you had your own family for support.
Your mother was so lucky that you & your family were there. Your love for her is obvious in what you have written here, & all the ways you have for sharing that with your daughters is inspiring.

My dad died from Alzheimer's 18 yrs ago. His doctor lied to my mom & said he was just getting old, nothing to worry about. That doc's the only person I've ever seriously considered murdering.... He put my mother thru hell.

I share your concerns, Lara, about the future. My dad's mother very likely died from Alzheimer's too. Dimensia, in any case. She, my dad, & I--all alcoholics, so I inherited at least 1 thing from them. I've got the gene for Alzheimer's (discovered in other testing).

Eric, thank you for telling us about your mother & your family. It makes for a beautiful story.
