Waiting is one of the hardest aspects of cancer treatment. On one hand, you feel everything is on hold. On the other, you are worried things are getting away from you. @arpie is right, try taking one day at a time. Things may be clearer next week. I went back to work one week after my mastectomy - my surgeon suggested two weeks off but I felt well, I was healing well and I knew that getting back to my work was a good thing for my state of being. He was fine with that. It wasn’t just financial pressure (I had plenty of leave available) but feeling normal again. But my job did not require a lot of lifting or carrying stuff and I had a very supportive boss. So hang in there till next week and remember your surgeon wants to see you recover - his/her advice is important. Best wishes.
