I'm so tempted to become a rebel?

I'm 14 and my mom doesn't take me seriously, much less pay attention to me. Well, I'm home alone right now, and I feel so rebellious. I want to do something bad. Nothing illegal, but bad. Like piercing my lip or something (I've always wanted to and she'd get pissed.) I don't know. I feel so stupid, but if she's going to treat me like someone who can't be trusted, that's what I'll give her. What do I do?
