Drive-aphobia

I've been noticing something. Ever since I hit that stupid deer, back in April (or May, or whenever it was!) I've been terrified of driving. It's not so bad around the house and stuff now, but when I'm going to (and from) class on Wednesdays my heart is in my neck the whole time I'm on the road. Every time I see the slightest bit of a road hazard, or whatnot, I slam on my brakes. Will this madness ever stop?!
