Glad your ok. As others have said, it's just a car. And good job on manning up to it. At one point or another, we've all done stupid things.
I'd say now is a good opportunity to start looking into doing track days and/or autocrossing Not only do they help to get the need for aggressive driving out of your system on an ongoing basis, but it helps you become a better drive with much better car control skills. And it's done in a safe and controlled environment, especially the autocrosses.
