Wishing you a successful operation on the 4th and a speedy recovery @Angiebloom! Of course no time is a great time to get the BC diagnosis but this time of year sucks :s !
I was diagnosed also in November and had my op in December , 3 years ago. Christmas dinner was switched from my house to my brother's which took the pressure off and helped me in my recovery so do what ever you can to let your relatives/friends take the load off you this Christmas.....and into the New Year when your treatment starts. If you look through the threads there are discussions on how to get your kids to help out too. All the best , J x
