What I have to *** has mostly been posted already.
Though I will say this.

It's frustrating when you pick open a wound, and it's bleeding, and you're stuck in school without any way to stop it or cover it up. Can't lick the blood off, people'd see that. Can't throw my sleeve over it, my mom would see the stain on my shirt. Can't walk over and get a tissue to mop it up a bit, becuase you can't cover it with your sleeve while you're going to get the tissue!

Plus, you go through band-aids like they're going out of style.

And now that my mom caught a glimpse of them (though she clearly doesn't give a... ._. you know...) I feel ashamed every time I'm around her. And afraid. Wondering if she's just going to bring it up, and hoping she doesn't. And I know it hurt her, even if she won't show it.

I feel ashamed whenever I'm around anyone. Like "I'm doing something, and you'd be upset if you knew what it was". It's really like a dirty secret. Skeleton in your closet. Something that you're ALWAYS working to keep hidden, so that more people aren't let in on it.

It doesn't solve the problem. It's just like drugs and alcohol. You do it and while you think it's helping, it's slowly making you worse.
