How to get over this fear?

I’m afraid of driving on busier streets. Like streets with an increased speed, lots of stores or strip malls, and stop lights. The factor of my driving only plays a tiny amount into the fear. I’m pretty confident I my driving ability it’s just the other drivers. A lot of times they’ll be on my bumper, go around my car when making a turn and all that and I’m going the speed limit. Does anyone know how to overcome this? This fear is really limiting my life. Out of 3 1/2 years with my license I’ve driver furtherest of 6 miles and that’s today
