Hi Jensen, you are experiencing very normal feelings. It is a huge shock & overwhelming in the beginning. I was diagnosed last July, lumpectomy & sentinel node biopsy & then mastectomy & axilla clearance with 3 cancerous nodes. I did 4 x AC & 12 Taxol. I work 3 days per week & worked all the way through with 2 days off. I was worried about immunity too as I work in a Dr's clinic but was lucky to not catch anything. I had bad days but didn't suffer too much. Everybody is different but I think you can plan to work & just see how it goes & if too much then cut down your hours or work less days. My employers were very supportive & in the end it worked out.
