Sorry to hear about grandmother, CLandrum.So sorry for your loss. I lost my grandmother who may as well of been my mother in 2000. She had a major heart attack in front of me while I was 9 months pregnant. I hate to be the cliche but it does get better over time. I am so glad you found a good way to get "out of your head" for a little bit.
I think it was Dr. Oz who was talking on his show once about the power of vacations/roadtrips. They don't have to be drawn-out, elaborate, expensive, etc. But simply taking off for awhile to get a change of scenery is great for both physical & mental reasons. The same can be said for laughter & simply feeling happy. Likewise, a getaway to WDW does all three in one.
