Dear sbee,
My heart goes out to you, please try and call your cancer team or maybe the breast cancer nurses on this site they are so caring and understanding, (0808 800 6000) I know this sounds very easy for me to say when your feeling so rough as the moment.
Is there a good friend or a family member who could help you or maybe attend your hospital appointment with you.
Wishing you, well my lovely lady,
with the biggest hugs Tili
