All of these things happened to me for the first time today. I was very nervous. I was at the bus station going from one bus to another when I first noticed it. The sounds on the bus got quieter. I got off the bus and went inside where rhe offices are and got some water. My head didnt feel right. It was just weird and scary. I dont know what may have caused this. Maybe it was something I ate. Or maybe the fact that my knee has fluid in it. I have no health insurance,and cant afford to go to a doctor. Atleast I know im not by myself tho.
