英文小作文：

I was playing football with my friends when I got hit in the head by the ball. I felt dizzy and my vision was blurry, so I knew I had suffered a concussion. I went to the hospital and had it checked by a doctor, who prescribed me some medicine and advised me to rest for a few days. I was scared and worried about what might happen to my brain, but I also knew that I had to take care of myself and recover from this injury as soon as possible. After a few days of rest, I felt better and was able to return to normal activities, but I still remember that experience and how scary it was to think about what could have happened if I hadn"t been wearing a helmet. I now take safety more seriously when playing sports and always wear my helmet to prevent myself from suffering another concussion.
