Deer in Headlights...

This morning as I was running late for work... I thought, ok I should take the freeway... but then I said no it'll be easier to just go the other way, the lights will be green. Well of course I ended up waiting at a couple different red lights for what seems forever as there was NO traffic the other way... again it is 6am and everyone else is still sleeping in their beds. So I finally get past walmart and can drive 45-50 mph. All of a sudden I see a deer right in my lane and of course I freaked when it didn't move ... and so that I wouldn't hit it, i swerved like crazy and lost control of my car.
This wouldve been different if i was on a road that was 25mph but no I was going pretty fast. This was right outside of my work too. I lost control of my car as it went back and forth and seemed like my car was going to flip. I got into my parking lot and just busted out crying because I was so shaken up. I finally went into work and my hands were still shaken because well... ive never lost control of my car before. The whole time after that, all i could think about was what if another car was coming the other way and I couldn't swerve out of the way or If i hit that deer and really messed up my car, and possibly me.... i've heard some freaky stories about people hitting deer and people even dying but... ok now it sounds like im being dramatic and what not. But i couldn't help but think of the different possibilities that could've happened....

Why didn't I just take the freeway???
