Hey Miss E, you lean on US. That's what this website's for. Breast cancer is isolating and lonely at the best of times, let alone when you have no family with you.
There are lots of services available, and support. The Look Good Feel Better foundation is great fun, and I found it surprisingly comforting. There is comfort on meeting people on the same road as you. Plus you get some fab free make-up!
https://lgfb.org.au/The Think Pink Foundation (in Docklands) is excellent. It provides all sorts of free services and workshops to people with breast cancer. They're really nice and kind there with a breast care nurse on staff.

We can't solve your living situation but we can be with you every step of the way. We've got you. Big hug, K xox
