I am sorry for the shocking news. That is a pretty sudden and short prognosis, but it is just a prognosis and is based on what the doctor has experienced in most cases.
Looking up Venetoclax, it looks like it has been used in two ways, both in combination therapy for AML:
Venetoclax + Vidaza or Decitabine
Venetoclax + low dose ARA-C
The first combination had response rates up to 73% and the second up to 62%. I think that it would be worth checking to see if your doctor or another may be willing to look it up and see if you fit the criteria for treatment.
