(((buffybike))) That's the worst! I got sideswiped a few weeks ago, and yes, you will be nervous around cars for a while. I also was depressed right after. I was quick to get angry at cars for a few rides. It gets better.
It's very frustrating, isn't it? You're out doing something you love, that is supposed to be good for you, then bam, you're in trouble. I found it really annoying when my friends told me how lucky I was, so I won't say that to you. Just take it easy, be gentle with yourself, and know a lot of us understand. I felt much better after talking to my lbs guys, so if you're friendly with your shop, they may be a good place for support.
I hope you feel well soon. I'm glad nothing is broken. How's your bike?
