Have you talked to anyone about your symptoms? It may be possible to alleviate them, it’s certainly worth trying. Do you have a breast care nurse? Or oncology nurses at your day treatment centre may be able to help too. You may also wish to talk to
a counsellor, it can be helpful to talk to someone outside your immediate family/friend circle about how you are feeling. Cancer and treatment are not exactly morale building, most of us can do with a bit of help from someone experienced on the way. Take care.
