What to do for a corneal abrasion?

I got something in my eye yesterday. it was probably dirt. i spent about 20 minutes looking in the mirror, but i still couldn't see anything in my eye. i used lots of eye drops, water, etc. my eye still hurt a lot but i toughed it out because i was at a friends house. my eye is sensitive to light so i kept it covered and went to bed early. this morning it still hurt, so i used more water and eye drops.i also noticed that my eyelid is really irritated and red. it is covered right now by a wet towel, and my vision has become blurred in that eye. im pretty sure that it is a corneal abrasion, but i don't know how to treat it. should i go to the doctor? is there a way i can treat it by myself?
