I'm very moved to hear of your illness. As the majority said above that you should definetly seek another opinion in case you aren't getting the correct treatment.
No one knows when their time is up SubhanAllah, nobody is of this life anyway, I hope while you actively fight this illness you pray to Allah almighty rightfully for help and mercy in this life and the next.
