Oh Leslie,
I am so, so sorry to read your post. I hate to use the cliche, "I know how you feel," but I do. I know where you are right now, with your emotions, as I have been there too. Please know that we are here for you, and we are saying prayers for peace, both for you and for your dad.
Mom was just saying yesterday, "You know, I have often thought what really good has come of your dad's cancer," and before I could look at her in disbelief. she went on to say how we as a family are closer, bonded, more faithful to God, and on top of it all...better friends.
Stay strong.
Blessings,
Jen
