I am so unreal.

I never felt like such a hypocrite.  I've become so lost in everything that everyone thinks I am that I'm really not sure what "being myself" means.
I've cheated on homework.  Not mine.  Riley's.  Yeah, he goes to school with me now.  Well, yesterday, something "came up" and he asked me to do his math homework.  He paid me $10 up front, called me a life-saver, and hugged me.  Ten minutes after he left, I broke down.  My mom was bothering me about going dancing that night (I've gone dancing every Wednesday night since I found out about it) and about the campout this weekend (which I cancelled today because I have a chem test on Monday) and about my grades in general, which aren't even bad.  So I packed up my books (and his book on finite mathematics) and got ready to leave.  As I was putting on my coat, Eric came up (I'm actually not sure why - probably to ask why I wasn't over on the floor) and I told him before he could say a word that I had too much homework.  I didn't cry.  Then he said it was okay and he would see me later.
I walked around campus, actually crying at this point.  I hope no one heard.  There weren't many people out, and I was fairly quiet.  Anyway, it doesn't matter.  (Everything in my head is rebelling at this point, because I never talk about crying, which I rarely do and don't approve of as a rule.)
What matters is that today I did his homework again, because he said he didn't have a computer.  I don't know if he's just making excuses or if he legitimately can't do it (there are definitely computers at the school, but this is Riley - he has issues sometimes), but it's making money, and pretty quickly (especially since his math is really easy).
But I feel terrible.
