Wow this was incredibly moving. I am sorry for your loss but I am happy you have such fond memories of your mother. What she did for you was amazing. It looks like the theme of the day is "putting your children ahead of yourself". You mom is a perfect example of this essential motherly trait. I think you mom just reminded many people on here how lucky they are to be able to call their mom and say "thanks".
Thank you so much for sharing this story.
Happy Mother's day to all of the mothers in your life.
