Biopsy

Hi, I recently found a firmness in my breast. It only felt slightly harder than on the otherside. Then it got worse and I went to breast clinic on 6th Oct. I was told there and then that it was  breast cancer. I was told 2 week wait. The 2 weeks passed and then I was told 3 weeks. I feel like my world is crumbling and the wait is torture. I have no one to talk too. Is this normal to feel like this. I am still working and struggling.
