Im 12 years old and a girl, and for some odd reason, I havtn been able too sleep, i havnt slept at all for 3 days. And now it seems one of my eyes feels diffrent and smaller than the other. Im not sure if it will be a problem if I dont see my regular doctor, or what kind of side affects of me not being able to sleep at all. Ive tried laying down closing my eyes for several hours, and I still cant sleep.
