That is crazy, they cancelled your appointment without even trying to get the confirmation. I am sorry your back gives you so much pain. I deal with chronic pain so I understand, if things get too bad then go to the ER for pain meds.
Wish I could help you with decorating and shopping. I don't enjoy doing either so I do it as soon as I can to get it over with. I laughed today because all my shopping is done but Robbie got an invitation to a birthday party right after Christmas so I was out shopping for that gift...
