My Mysterious Illness

The following has been condensed for brevities sake...

.

I've had a low grade fever since June. I have never had a fever, unless I've had a bad cold or flu until now. My doctor tested me and found out that my white blood cell count is very high - 18,000. Thursday I had my blood drawn for another test. If this test is positive, it will mean that something is definitely wrong, and I will have an idea as to what the disease is.

.

I got on the web and looked at the possible reasons that I could have an 18,000 WBC with fever. My eyes went to the worst case scenario, (of course), but when I saw it, it made perfect sense.
.

My intuition says that I have the disease, but I hope that I'm wrong. It's a bear of a disease that I couldn't wish on my worst enemy, (if I had one). :) I'm eager to get the blood test results. I want to know exactly what I have ASAP, but what then? By the way, I still don't have medical insurance. I go to a free clinic.
