I fully understand how you are feeling as this happened to me las year.
I had a lot of support from the hospital and friends, plus several who had also had breast cancer.
I wrote down lots of questions and although I was a nurse/midwife at the time and probably knew too much I had to put my hands in the care of the professionals as they knew best.
Take each day at a time, talk about your feelings and concerns, don’t bottle them up. It does take time to sink in, but just be thankful, they found the tumour when they did and you are getting early treatment.
People don’t know what to say, but do talk, it helped me.
I’m now a year on, gave up work and decided to live my life, it’s so precious.
Thinking of you and good luck on 26th August x
