@nikkifrn - my dx was different (I'm triple negative) but I was able to work through chemo and radiation. I had chemo treatment late on Thursday afternoon, worked a light day on Friday, slept in on Saturday and started feeling better on Sunday and returned to work on Monday. My situation was also during part of Covid and I was able to work remotely. I only took off time when I had my bilateral mastectomy. I read about possible side effects and planned accordingly. For chemo I kept candied ginger on hand and ate high protein meals (so I won't miss a treatment); had a port implanted so my hands were free during chemo treatment; I took music, knitting and my iPad for every treatment (I made a chemo bag) so where ever my mind went I was able to change focus to things if there was no one to talk to at the time. As mentioned I also worked through radiation. Again I was able to schedule my radiation treatments at the end of the day on Thursday, again had a light day on Friday, treated myself to extra rest if I felt the need on Saturday and returned to work on Monday.
