Hi Dear!
I felt like you were crying while you were writing it.
I am an oncologist. I have seen so many terminal patients. It is not an easy sight. What you are going through, is not easy.
Palliative care is where we believe what can we do best to ease the breaths of the patient,ease his pain, where he can atleast eat and drink on his own ,go to washroom on his own.
Next Steps
So, The condition which you have mentioned looks like a metastatic disease requires palliative care.
