A caregiver, in a sense, also has the cancer, although they don’t have the symptoms or treatments. They have the same emotions as the patient.
It is difficult to know what the treatment feels like to the person who is going through the cancer or how much worry that person has over the cancer. For me, I try to understand from their viewpoint as best I can. I try not to make the cancer treatment more difficult than it already is or let on how worrisome the cancer is for me.
