Ditto to what Dotsie. Death is difficult, even when expected. And I don't care how old a person is, it still isn't easy. I think of sayings loved ones used that died in the 60s. The death of my adoptive parents and grandparents left a hole in my heart big enough to drive a semi through.
I'm sorry your friend lost two close to her in a short span of time. Prayers that both of you are given the comfort you need, have been sent heavenward!
