Kat,
I had a very similar situation so you are not alone. My father became ill on Nov of last year but never did I think he was going to get sick to the point of hospice. I was scheduled for surgery on March 3 with my Upper gi scheduled for Feb 13th. On Feb 1 or so we started a bedside vigil with my dad and hospice. I had to cancel my upper gi on Feb 13 because my dad passed away on Feb 12th. I had to reschedule my surgery which I had on 3/24 and i am doing well. I know that empty feeling that you have since I was also so preoccupied with my dad. We will get through this and in the end we both will be better people. I will keep you in my prayers.
My friend keeps telling me there is no feel that tastes better than skinny feels. Lets see if she is right......
