Did I fry my car?

[x240xdrifter]

so the other night, not paying attention I put my terminals on backwards and try starting the car, and then relaized how stupid I was and turned the battery round, so long sotry short, nothing electrical works in my car except my starter which clicks and the turn signal lights in the front, the rear lights don't work, the radio doesn't, the digtal clock lights up but doesn't tell time and so forth....am I screwed or can I fix it?
