It sounds to me like you may have been scammed by a couple of thugs. They were probably waiting, with their lights off, for you to back up, and quietly rolled up on you. The fact that their hood friends came from inside the house to harass you only fortifies my suspicion even more.
Even if you did just fail to notice them, you can't let it get you down... Why just today, possibly at the same exact time as you were facing your ordeal, I blew out the engine of the car my friend was lending me until I can get my van back on the road. I knew there was an oil leak, and I should have been checking it every day. But I only ever check it when it starts to act like there's a problem. What's worse, he was really cool about it when I broke the news, so that packs on the guilt even more.
With the exception of fearing for one's life, I think I'd rather be in your shoes. I wouldn't feel at all guilty about damaging a car that was likely stolen, by a bunch of stupid, aggressive savages.
In the end, in either case, it's all stress and we can't let it overwhelm us. Keep your chin up, my friend!
