My dear friend, I lost my two sisters, my little one my angel who came to this earth to teach what love is and had a smile that made you feel so good and two years later my older sister, two years later my mother you feel that your world had ended, I cried for them a lot, but something that helps me is to remember the best of each one, their worlds, our great times together but most of all our long or short conversation, I am sure that you are doing the right thing by saying until we meet again...that is our greatest hope.
It sounds like your sister was a very special person, and the two of you shared many happy moments! I'm sure she hears your words and is smiling down on you. God bless you both!
