Sorry to see you here, @Jodles - Yes, it is always a big shock when first detected, let alone diagnosed ...... I had my surgery in Mid Jan this year, so am one year 'ahead of you' ....
What I can say is - you WILL get thru this & we are here to help you do that. Any question that you have - whack it up - no matter how trivial you may think it is - someone will jump on & reassure your, or suggest ways of dealing with it ....
Try and keep BUSY over Xmas & New Year (the best thing to do!) and then deal with the surgery in Jan!
Take care, thinking of you & the family xxx
