bloody 'ell mate!!
at least your not seriously hurt. I think the risk of riding a bike is outweighed by the sheer fun and the feeling of being truly alive.
I had a serious accident in '92, arm in peices and a cracked spine. but I came back into biking cause I missed it too much, abet i don't bike to commute just to have fun.
you'll be pissed off/depressed now, so don't make any rash decisions!
