I am so sorry to read about this wonderful ladies passing.  She was an inspiration to many of us.  My condolences too the family.

Dear Mom,
I was blessed to know you and have you in my life. I have fond memories of our short time together.  I will cherish them for the rest of my life. Your laugh was contagious and your strength is something to envy. You will be forever missed. I know that you are much happier now and that brings me great comfort. RIP Mom
