You have plenty of options in the food service industry, and not all of them even involve cooking. Your only trouble with finding the appropriate career path will be experience, and money. You may have to work as a line cook with catering as a side job for many more years before you have the customer base and reputation needed to run a catering business. Management is another avenue, but it's one that requires lots of experience both cooking and supervising. You also have to have experience to get certification, which you may or may not be interested in.
If you're not in this business for the long haul, don't even bother getting into it. If, however, you could see yourself building a career over your entire lifetime, working crappy hours, and never making quite enough money, then it might just be a rewarding career field for you.
P.S. I've never met a chef who wasn't an alcoholic.
