It's weird to go near my mom....?

My friend made a bet for 50 bucks that i couldn't write a "more vulgar" rap than he could... dumbest idea ever, i know. But anyways, I went ahead and wrote the most explicit, dirty, and disgusting things that i would never say to anyone or anything; I just wanted to win the bet. But I accidentally left the pad of paper on the couch and my mom saw it- all the details and all. She yelled at me for being a disrespectful moron and said she was embarrassed to be my mother. But I mean I never wrote that thing intending for anyone to see it, and i left it inside a closed journal notepad that I got last christmas... so she kind of went in my personal stuff without asking. Now it's so awkward to go neat her because of what she saw... what do i do???
