HI @Bowie - we are all thinking of you for tomorrow and sending you virtual hugs, hopefully you can feel yourself surrounded in our warmth and understanding.
It is hard, losing your breast(s), but you will now be moving into the next phase of your healing and recovery.
I know the most anxiety I have felt is in the lead up to the op(s) and then, as @melclarity says, I feel a sense of calmness and control wash over me on the day. The surgeons, the nurses, all the staff, your family and friends and all of us here only wish the very best for you. You will be looked after by experts.
Take care. You'll be in my thoughts throughout the day. Please let us know how you go Nikki xxxx
