Alicia -
I worked all through treatment (chemo/herceptin and radiation). It wasnt my first choice, but my husband pointed out that we needed to maintain our lives, that I shouldnt give in to cancer and treatment. After hearing that, I felt like if I stayed home I would have too much time to think... so, off I went.
Some mornings, I would stand in the bathroom, fresh out of the shower and cry my eyes out and almost give in to the bed or the couch, or my bathroom floor.
I would have treatment on Thursdays and be back to work on Mondays, until around my 5th of 6 treatments, I had to take Monday off and probably should have thrown Tuesday in there as well. I scheduled radiation for 7:30 am and went to work right afterwards.
Looking back (a little over a year now), I am glad that I went to work and pushed myself that extra little bit, but I believe that we all know how much we can handle. I say if you need a day -TAKE IT!!! you totally deserve it
