Melissa,
Aren't friends great?!? It sounds like your life has been blessed by them I've always liked the saying that "friends are the family you chose for yourself". I am glad for you to have people in your life like this.
I also lost my father this past July, and although I am quite close to my family, my friends and FI were my rocks during my grieving. In fact, Daddy only met my FI once, and died 7 days later. I am sure both of our Daddies are smiling down, and know how happy we are. Take care of yourself, and feel free to PM me anytime if you want a shoulder to lean on
