I'm BLIND!!!!!!!!!!!!!!!!!!!!! :(?

...so this morning I was putting on mascara and my sister banged on my bathroom door and scared the **** out of me and the brush poked me right in the eye! It hurt SO BAD! I'm seriously not just being a baby, I can't really see out of it. It's really blurry. Is it possible to scratch your pupil? Or cornea? retina? lol :( HELP
