Lately I've been feeling quite tired, and I am thirsty/hungry all the time. But just this morning I woke up feeling like hell just hit me. My vision was blurred, I was feeling really dizzy, and my fingers and legs were shaking. I went into the bathroom to go to the bathroom and brush my teeth. During brushing my teeth, I felt like I was going to vomit. But I knew I wasn't sick, because this was a totally different feeling. So I layed down on the floor, for about five minutes with the pain. After it passed, I got in the shower. I was fine for about 10 minutes. Out of no where I started to feel my head and arms get really heavy. My legs started to give out on me, so I sat down in the shower. Once again, I felt like I was going to vomit. Soon, the same even occured again, only with more pain. I eventually got up. Right now, my fingers are shaking and my feet are shaking. What's wrong with me? I'm starting to get a bit scared.
