My friend accidentally elbowed me in my right eye yesterday now my eye is hurting so bad idk what to

Go see a doctor if it hurts that much. If your friend for real did it accidentally, then keep being friends with him/her. If on purpose, then try to work something out, like why he/she did it, and you can choose whether to stop being friends or just forgive and forget. I say both if that because idk if you want an answer for the eye or for the friend.
