Getting back on the bike after a crash can be tough. Especially when you have a long healing period off the bike first.

When I had my first wreck I got back on the bike the next day. I had some road rash and bruises, but not enough to keep me off the bike. Getting back on the bike immediately was helpful.

There are two schools of thought in psychology for getting over fears. (I'm not a psychologist)

1. All at once. Basically, the first day on the bike go do a 50 mph descent with cars everywhere. This one works for a lot of people, but is VERY scary to do. IF you did happen to crash while doing this, you would probably be a LOT more scared then when you started. I don't recommend this method for an activity where you can't control all the variables, such as cycling.

2. Gradual. This one would have you starting out slow and building back up to where you were. Start out going to a parking lot to work on bike handling. Show yourself that you can still control the bike perfectly fine. Go for longer rides. Ride more days. Increase your mileage back up to where it was. Take corners faster each day until you're back to where you were.This style takes longer, but works for a lot of people, and is unlikely to fail miserably.

Also, do some introspection. Maybe you simply don't enjoy riding enough to accept the inherent risks. If you decide that you DO enjoy riding, talk to yourself about the risks. Think about worst case scenarios (this works in ALL aspects of life when you're nervous). Example: You're scared of public speaking, so you think about "what's the worst that can happen?". Well, you screw up, some people laugh at you. Big f'ing deal. You'll live.

So you're nervous on the bike. Think about what's the worst that can happen? You fall at 30 mph and break a few bones? Ok. Bones heal. You'll be off the bike for a couple months maybe. Scrape off some skin? Well, it hurts, it'll leave scars, but it isn't going to kill you. Pain is all in your mind, learn to own it and the road rash doesn't own you anymore.

Good luck. Hope you get back on the bike (horse) soon.
