My deepest condolences to all who lost their Mother. Mine passed away in 1989 and I still think of her every night.
I know how all of you feel. I lost my mother in 2007 and my other mother (in-law) on my birthday in 2009. My mother had dementia and the last year of her life, she thought I was my Dad, who died in a car accident 10 years earlier on his 73rd birthday. I was lucky enough to have my mother. She cared enough about me that punished me when I screwed up. She was the most happy when 3 of her four children had college degrees. When I was young, I spent many hours in a corner of my bedroom. Yes... That's my mom. I love and miss her.
