Thank you for posting your memories. You had a wonderful mother who lived a long and good life. It was a blessing that you were able to care for her.
I have had that honor as well, with caring for my dad for the last two years of his life, and my mom continues living with me, now for 9 years. It’s not easy, to say the least, but it’s well worth it. I will never regret it.
May the Lord bless you and comfort you in your grief.
