Im currently in the middle of my year 11 GCSEs and over the past few weeks of them I've been getting stressed which has now lead to me being sick 3 times during an exam today being sent home and I'm required to go back to do another exam later on. My school isn't giving us study leave but I was wondering because of my diabetes and the sickness would my mother be able to request study leave for me so that I can stop stressing out and get back on track?
