Every person has some difficulties in their life. But when it comes to life and death question at that time there will be no language to say what will be the condition of mind. I have no words to console you but as a Muslim I can say that anything is possible if Almighty Allah want. I have seen many serious patients who were turned away from the hospital because they thought the patient might not live much longer. But later they were completely recovering the illness. So trust in Allah and try to better treatment Inshallah  Allah will make you happy.
