Fade To Bleh

I'm a very obsessive person. I went on one date with this guy, and it was immediately apparent that he's emotionally unavailable and broken. I deleted his number but soon dug it back up. I texted, but he never responded. I know he's bad news, but I still think about him constantly. It's especially bad when I'm trying to go to sleep. How do I stop these intrusive thoughts?

It's like that spinning teacup ride, with Satan as the carny: "Wanna get off? Too bad!"

You're doing your best...
