Hi Jessica,
I'm in a similar situation to you. i was diagnosed on 5/12/13 with DCIS and had a wide local excision and sentinel node biopsy. Unfortunately, clear margins weren't obtained and now Im booked in for a mastectomy tomorrow. I found out on 20/12 that I needed more surgery and then everything closed for Christmas. I am grateful for the time as I have read a lot, talked to breast cancer survivors, had heaps of support from friends and family and now i feel prepared for the next step. I don't know what treatment will be advised after my surgery yet, so still unsure how long I will be off work. I had 3 weeks off after surgery and recovered well. I now have a plan, workwise, and i'm not worried about work anymore. Now i can concentrate on my health and doing whatever I need to beat this breast cancer!
I have found exercise, music and deep relaxation to be really beneficial for me. I am feeling feeling fairly calm, but naturally anxious about tomorrow's surgery. I have found this network to be reassuring and informative. The women are all brave and honest sharing their stories.
All the best with your treatment.
