Eye problem

I am feeling so tired now yet I am not able to sleep. My right eye is feeling so uncomfortable when I close my eye. I feel that there is something in my eye. Whenever I close my eye, my tears keep dropping. I am afraid that I hurt my cornea. Oh my god. What's wrong. It could be allergic too. Pray that my eye is allergic. I WANNA SLEEP BUT I COULDN'T SLEEP. PLS HELP ME.
