Nowadays it is not quite as hard to get into graduate school. Often if you have an bachelor degree you can at least start many online/distance education degree programs from accredited schools and prove yourself as you go. I'd take a couple courses online so you can work more on your own schedule, see if it is what you want and then, you can transfer to a brick-and-mortar school or take more courses, etc.
