@Chelley59 unfortunately, treatment is often a long road. Regardless of what your treatment plan is, you are going to be in the BC zone for some time. It's not something that can be dealt with quickly and then you go back to "normal".
Everyone's plan is different, depending on their situation. Mine: Friday 30 will be my first anniversary of diagnosis. 20 days later first consultation with surgeon. 8 days later medical oncologist, when her advice triggered me to refuse surgeon's desire for me to have chemo first. Then followed a heap of scans etc. and Hormone Blockers (Letrozole) for about 5 weeks while I waited for surgery mid-Feb. Chemo started 3 wks later - I did 20 wks. A few weeks' break (during which I took Letrozole again) then 25 days of radiation. It was a long slog. Now on Letrozole again until whenever. Implant changeover surgery will be in March-ish.
We all have our own particular pattern of treatment and reactions. But usually there'll be someone on this forum who understands what you're experiencing at any time. Just share. Wishing you strength.
