Feeling uncertain

Hey there! More medical melodrama. Enter at your own risk.

     I'm still not sure what I feel. A week ago, I went to the doctor for a follow-up for a minor infection. While I was there, the doctor decided to run some routine blood tests. Fine. Whatever. No problem. But...When I went back a few days later, it turns out that some of them were a little off. So, they sent me for additional blood work. To find out if I may have an auto-immune disorder.
     They ordered these tests on Tuesday. I heard it takes about a week for the results to come back, so I have to wait a while to find out what is happening... I know it can be serious or it can be nothing, but knowing what the doctor is looking for is still a shock to the system. I don't know how I feel. Or how I should feel.
     It didn't help when I took my confusion to Facebook. Someone I care about very much told me that I was overreacting by being concerned. I expected jokes from a lot of my friends, but this person should know better how it feels to be frightened and confused and overwhelmed.
     I'll keep you posted as I find things out. Thank you for reading this far, because it tells me that you care.
