Just came across this and boy was it touching. Seemed a bit rushed at the end, maybe you spent a long time writing this?
Regarding your mum, she truly sounds like a super mother and you have been blessed to have been mothered by her. I hope all the loving and positive attributes of your mother rubbed off on you and your siblings and you in turn will share the love with your neighbours, friends, family and relatives.
My mother is also very much like your mum was, very loving and selfless.
I hope you celebrate the life of your mum in your own special way.
