Not sure if this may help you, but I believe you can be on a few waiting lists for surgery. I have been on a waiting list for some surgery for three years, but I may see if I can go on multiple waiting lists in metro Melbourne. It does "stink" having to wait for surgery, especially cancer related surgery. Probably no harm in seeing if hubby can be on multiple lists and in the meantime see if you can get a housing support worker to source permanent housing on the grounds of you having mets and husband's situation also.
I understand the toxic work situation having been through it myself and I am sure this contributed to my cancer diagnosis. Do look after yourself and I hope some doors open up for you soon. I agree, don't stay in a toxic work environment, been there done that, it really doesn't do us any favours, that is for sure. Best wishes and hoping all the best for you and your hubby. Take care. xx
