Recently, I have got some symptoms. I can’t see things clearly. When looking at buildings and words, I feel that they are moving. When I look at some write things, it seems that they are shining and keep changing bigger or smaller. If I keep looking at an article more than 2 seconds, I can still see it in my eyes even I have turned my eyes to the wall. My heartbeats become quicker than the normal and my body temperature is a little bit higher. Sometimes I even want to throw up.
