A question about working for MYSELF. I never thought I'd say this but I'm interested in designing clothes.

You'd be better off doing a screen printing course, or searching google for tutorials. Don't wast thousands of dollars of dollars on a fashion design course if you only want to do shirts, you're not going to be employed. They take a year for a regular course, a year and a half for master. Full time. You could try selling them at markets/malls if you make them yourself.
