I feel like dying

For the past week I have been dealing with a serious sinus headache. Last Sunday you could have told me that I had black plague and I would have believed you. I have never felt so bad before in my life. I seriously thought that I was dying, like I thought that a bug had gotten into my head, and was trying to get out. No sleep, waking up feeling like I was sleeping in a sauna, it was freaking horrible. But luckily I am getting better.
