OCD.
I think I have this, too.
As of late, I've been drawing these, how do I describe it, um, rhombus-shaped things. Sometimes they're small, sometimes they're huge, and sometimes they're uneven, while sometimes they're even. They've been all over my schoolwork since November of '10. My teacher even called me up to her desk one day to ask me what they are. I told her I had no idea.
Hell. I'm drawing one right now as I type this.
Please help me.
