Hi Bea!
Don't worry, your confidence will come back with time and practice.
I was terrified too for the first few months, one day I had to be at work at 6am, could not believe how easy and relaxing the ride was.
Like others have said, practicing on the roads early in the morning and late at night will boost your confidence. I used to take the pavement or the park shortcut during rush hour, but you will soon realize taking the road is mostly quicker!
The bike gives you much freedom of travel when you don't have a car, so don't give up.
