Breast Cancer Treatment Starts Next Week - Confused

Hi, I know I'm luckier than most and the NHS are fantastic, but I'm confused and it's not helping with the stress. Went for pre- admission today, all OK, but only home and call to say admission brought forward to next week! Was supposed to be mid to late June. I'm OK with that, they assure me prognosis is the same,  but it is the extremes of info you get. Ward nurse talking about admitting me for the entire month of radio; Cancer Nurse telling me I can go back and forth every day for a month "by train". Imagine something between the two extremes is about right to expect, but oh boy does this mess with your head. Only diagnosed on 7th - complete roller-coaster. Be good to hear from anyone but PLEASE don't say anything negative!!!
