Force dear brother is not easy to see our loved ones leave since some day they will leave our side but always said that if they leave our side that is with a beautiful memory of us as true children who taught us to do our parents , she will be in a better place and in peace if she has any physical suffering, waiting for that day when they meet again, my advice is to fill her with love his last days and to tell her how lucky you have been to to see her as a mother.
My condolences for your early departure @winstonwolfe
