Sorry I saw this post too late.
I can't believe that.I was going kinda post the same question a couple days ago!
3 days ago, in the middle of the night I had a very sore throat, was coughing like crazy, runny nose, my tempature was 102. I'm still getting over it but that day after I woke up, Evrytime I got up to take medicine or even go to the bathroom, My head was spinning, I felt like my energy was absolutely depleted & had that passing out feeling like I never experienced before. On top of that my vision was getting very blurry that whole day-That never happened to me before that I remember. I'm really starting to scare myself. I really think I'm losing it.
