What Is The Life Expectancy In A Person With Low WBC Count?

I have been taking Firocet but 6 don't work because of waking u[ with headache. I have stopped taking it and took about$100,000 test in my cost. I am in the State of Alabama. Doctors seem like they are more concerned about there troupe as well as the pharmacy than treating the person. I went in the hospital with white cells of
1..... then 500 lower that one. I have been told I was going to die , then not how many can I takeif doctor approves?
