Bad driving habit

Yours truly never took the road test in driver's ed. Yet somehow the state of Florida gave me a license. Needless to say I suck at driving. It is really a bad habit. Sometimes I worry my self with my driving. This is why I am at home on a rainy Friday night. My bad driving plus rain does not mix. Actually I drive better in bad conditions. But it stresses me out. I need to practice my driving because it's so bad. I wonder if there is a range available for adults?
