Hello @Helen40,
Sorry to hear your treatment thus far has been so grueling. Is switching from private to public health something you'd consider for the rest of your treatment? The cost savings would spare you that extra stress and, as a public patient all the way through, I can reassure you that our public health system is excellent. You'll probably get the same doctors who do the private work. Disappointing re that breast care nurse. I had one like that, but there was another one who is much more pleasant - so now I only deal with her. See if there is someone else available. @FLClover is spot on re getting your GP on board for support and a Mental Health Care Plan. Ask about any other local help you could access.
Good luck. I hope you feel better very soon.
