sorry to hear of your loss.
Even though some time has passed it is still a significant event in your life.
It is something you will never forget. We only get one Mum.
Your post is a testament that you loved her very much. You shared a great love. She looked after you and gave you love. You gave it back in return. That is the best.
A loss of an estranged family member is worse.
Lots of love to you and your family,
