Hi Susie. Welcome to this page- you’ll get a lot of help here.
you’ll be feeling so overwhelmed- try to take a few deep breaths! Everything is new and complicated and a rush- hard to take it all in. Do try to take someone with you to all your appointments, at least at this early stage.
I can’t help with information about financial support, but the breast care nurses are great. Probably others will post advice in that area. The public system is very good for breast cancer treatment.
I just wanted to let you know I’m thinking of you. Things are difficult at present- you have every right to feel angry, sad, tired, overwhelmed! It may take time, but it will get better.
