I got bit on the finger by a wild rat. How fucked am I?

You'll see at the next full moon.

See a doctor, seriously. You can't treat rabies by. Yourself.

I'll go see one tomorrow then. I looked it up, isn't rat-bite fever more likely?

It's not likely you'll get rabies but you should get the shots anyways--rabies is pretty much 100% fatal so it's better safe than sorry (once you start showing symptoms, it's too late.)

And of course, there's always other infections and whatnot to worry about. So you should definitely see a doctor.
