How can I improve my running

Hi I go to junior high and my p.e teacher is making us run 5 laps without stopping and walking. My mom said its just to get us in shape. But she does not know how long the course is. When I run I really over power myself to the point where I'm gonna faint. I don't know how to explain any of my running pains to my p.e teacher. He makes us do an extra lap if one person walks. It gets really painful when we have to run 10 laps. I really need help to improve my running. Any solutions to any of my problems would be great. Thanks if u answer my question 😏
