Denise,
What a beautiful dream, I bet you didnt want to wake up from that one..I wish I could help get you through the holidays, they are so hard I know, one thing that helps me is knowing that my dad wouldnt want me to be sad, so when you're feeling so overwhelmed with grief think of how your mom loved you so much and would not want you to be hurting..
I understand about the guilt you're feeling, I dont really know how to get through it, I think we will always feel that there had to be something we could do.. Its very traumatic for the family, I am not sure if time will ever heal that wound..You're not alone Denise, we're here..
