Do you have a case manager from your insurance company or a social worker from the oncology center who’s been working with you? It seems you’re really not getting the assistance you need throughout this journey.
You’re not ready for hospice but palliative care could be a good alternative for you. When you have your visit with the NP this week, talk to her about the possibility. Below is an excerpt from the Mayo Clinic site:

“Palliative care is specialized medical care that focuses on providing patients relief from pain and other symptoms of a serious illness, no matter the diagnosis or stage of disease. Palliative care teams aim to improve the quality of life for both patients and their families. This form of care is offered alongside curative or other treatments you may be receiving.

Palliative care is provided by a team of doctors, nurses and other specially trained people. They work with you, your family and your other doctors to provide an extra layer of support that complements your ongoing care.”
