Implementing changes are hard ... and 4 hrs is a long way to travel when you don't normally go out, so maybe to build up the confidence maybe you could start by choosing a place on the map to visit (an hr away) and drive there ... then somewhere 2hrs away ... etc, so you get used to driving further distances. This would build up your confidence, you'd feel you were doing something, and you will be able to drive those 4 hrs ... when you're ready
