You are in my family's prayers.
Do NOT let the place you are in, the doctor that told you this news, write you off and accept it. Our medical care in this country has been torn asunder into financial hawks and actual care. You MUST keep making noise until you find a place that wants to provide actual care and not "end of life care".
There are 3 major clinic/companies in WI. One of them is absolutely worthless besides ER triage care. They will get you stable and then tell you "sorry" and ignore you while they figure out the best route to get the most from insurance.
The second is a mix of good care and insurance fraud. At least they won't usually let you die.
The last, provides care and will actually diagnose what is wrong instead of guessing which pill they should prescribe "come back in a couple days if this doesn't work". (actually said this, not kidding, the first place)
A coworkers husband was prescribed pain killers for his back pain. Then he died about a day and a half later from the ruptured bowel he had.
A retired mother of someone I know was told she had arthritis by the local clinic and should take pills the rest of her life. 7 years later she moved, went to her first appointment at the new place, and 15 minutes later an x-ray showed she had a completely worn out hip and zero arthritis.
I could go on.
Right now, in this country, you must be the squeeky wheel until someone finally listens and does something. You keep banging on doors until someone actually answers and wants to help and not cash your insurance money and tell you "you are just too old".
You MUST be pushy and ornery and a general PITA until you find an actual care provider.
We will pray for you. It's all we can do, we aren't the doctors. Just make sure you fight for it, it's your life not theirs.
