Chris really sorry to hear that. from what I can give as some advice my partner was recently diagnosed with breast cancer, she had surgery to remove the lump and has since been going through chemotherapy. It’s tough for me and I can’t begin to imagine what she and you are going through.
We are fortunate to have had excellent care and fingers crossed the outcome will be a positive one. My partner is determined to beat it, after all she wants to be around for our 16 math old lad.
Take care, hope and determination will help you beat this as well as help and support from wherever you seek it.
