Bon, my sincere condolances to you and your family on the loss of your mother. I have shared a grief such as yours, I do think of my own mother daily, who also suffered the hardship of Alzheimers/Dementia. Sharing a poem someone sent to me in honor of all of our wonderful mothers.
"If roses grow in heaven, Lord please pick a bunch for me, and place them in my Mother's arms and tell her they're from me.
Tell her I love and miss her, and when she turns to smile, place a kiss upon her cheek and hold her for a while.
Because remembering her is easy, I do it every day. But there's an ache within my heart because I'm missing her today."
