So I was recently diagnosed with polycythemia and the doctors words were literally "holy fuck! They didn’t tell you this 7 years ago???
I’m having a very hard time right now because people with this condition are expected to only survive 20 years after the diagnoses. Meaning I have less than 15 years to live. I’ll never see my child graduate high school. I’ll never see them get married. I’ll never get to meet my grandchildren… this sucks. I’m so terrified right now. What am I supposed to tell my wife? What am I supposed to tell my parents? I’m going to die before all of them? How did I upset the universe to deserve this? I’m so scared and I don’t know what to do. L
With diagnosis 10-20 years that’s just statistics and statistics have outliers.
Second, after reading more about it I think OP doesn’t have to worry about it. It indeed says the prognosis is 10-20 years but the sample used for this estimate was ~60 years olds (most common age when the condition is diagnosed) and I think his doctor missed that part.
I would recommend to see another doctor to confirm this.
