“I bite my bottom lip until it hurts, and I love it. It’s a hurt I can control. I can turn it on. I can turn it off. If I bite hard enough, I’ll see the marks of my teeth. I prefer that to the pain that spreads over my body when I least expect it. That’s a pain I can’t stop—can’t control. And it’s invisible. Untraceable, but lately, it’s hurting me just the same.

I can’t see it. I can’t find it. I can’t fix it.”
