Ride somewhere different. If you know the places that cause the fear, you are going to build up mental blocks to riding them. Ride somewhere new or do your route in reverse.
No harm in taking the time to analyse the bits that scare you, but just remember that over thinking a problem will make it more of an issue. Relax and enjoy. Also, generally speaking, if you can hold a line that means the wheels are aligned, the bike will naturally work for you. Just make sure your centre of gravity is in the right place.
Go ride and enjoy …you’ll feel better.
