That's a bummer man. Only a few options really.
1. Don't ride
2. Come to terms with the fear and realize even the bus could have issues causing a wreck
3. Slow down on the hills. No need to ride 20-40 mph if you don't have to
Only you can decide what is best for you. I don't know the hills or the are so I would not feel right telling you to "man up" or what not about the fear. It is all up to you.
