Well to your credit the first step in solving a problem is realizing you have one.

It is fine to make mistakes as long as you learn from them and don't repeat them and of course you don't harm anyone in the process. The problem is, if you take greater and greater risks on the road then the problem will solve itself eventually.

Maturity behind the wheel takes time. The best drivers do not endanger others or themselves.

Perhaps you can attend some track days at a local circuit and get your adrenaline pumping in a safe way. Knowing that you have a track day coming up can go a long long way to keeping your foot out of it on the road.
