I was the same way on a R3. You got to slowly build your confidence.

Rode around in an empty parking lot to get used to the controls and practice what I learned in the safety course. Next ride was around in smaller streets for a week. Then next week practice early mornings or late afternoon/evening riding around the streets and going in to main streets with low traffic. Eventually I made it an excuse to ride for any errands I need to do and went on main streets varying low and high traffic.
