for your loss....
I lost my Dad serveral years ago to Cancer, and hadn't slept for weeks because I was taking care of him and my Mom.
DH and I decided to jump on flight with our airlines points, and go to Disney. At the time, my Mom wasn't ready. It seemed crazy to go, but really was the only place I could finally get relaxed enough to sleep. (and then was in a much better position to help my Mom with the business and other issues that came up).
6 months later... DH and I ended up taking Mom for a week to the Beach Club concierge, which we all enjoyed, and now 5 years later, Mom is remarried, and I have adopted a little 5 year old girl.
Hope things work out for you and your family,
God Bless, Goldi
