Sorry to hear about your struggles. After my right mastectomy I was on antibiotics for weeks! I had a final drain which they didn't pull out for ages.
Radiation was easy, 30 early morning appointments. I was able to cut down on work hours so I went home and napped.
The issue with this disease, no matter what stage we have, is fear. Your doctors are taking good care of you by ordering the PET scan. I was and am terrified each time a new blood is drawn or imaging ordered. As you know, it's to track our progression. I ask for Ativan before each MRI. I hate that machine. It gives me claustrophobia.

In the meantime I emphasize ME. I try to do things I enjoy, like taking daily ballet classes, skiing, spending time with family and friends. I have also dropped a few friends !! I realized those relationships were not adding value to my life. I seek out therapy to help me adjust to the new me with a definite expiration date. I try to emphasize the positive and have become more tied to my religion. Hope you find your path as well. Good health to you and blessings.
