When me dad died, there was no surcease for the pain for me but time - a lot of time, and still I feel the loss, in a more chronic way. I always will till I die. But you have been there before, and are now there again. I wish you and your family all the best in dealing with your loss, and to celebrate a life that meant so much to you, and no doubt to so many more.
My prayers and thoughts are with you, your family and friends during this difficult time. Cherish the memories and the love of your Mother, she lives on in you.
