@Nikkilee have you looked at the Otis foundation website? They provide free holidays for people up to two years post breast cancer treatment. You just have to get to your destination and feed yourself. It might be a way to have a break and take some family with you. Travel can be problematic if you don't live close to one of their numerous properties, but it's worth investigating.
I didn't work for nearly two years after my latest diagnosis so fully understand the challenges of limited finances, unemployment and unrealistic expectations about when you should be 'better'. Otis has been a godsend for me and others. Good luck and I hope things start to look up a bit for you. This is really hard work. Mxx
