I'm sorry to hear about your dad. I totally know what you're going through, as I just lost my mom over the weekend. I know all about the numbness that you are feeling. Just take it a day at a time, and hang in there.
I will keep you, your mom, and your family in my prayers. I hope that you can find comfort in the memories of your dad.
And don't forget the DIS folks are here for you. They are so incredibly supportive. They've really helped me, and I'm sure they'll be there for you as well.
Karen
