You say you like to play on the computer. How about a career doing something with computers? There are 2 year programs for that. I had a friend who took a program at a community college for debugging code. It paid a decent wage and didn't involve long study.

My daughter is in college and didn't know what she wanted to do. I took her to the college bookstore, textbook section, and told her to just wander around and look at all the books and see if anything sparked her interest. And then to take a class in that subject. Maybe if you did that, it would help you uncover what your interests are.

Good luck.
