I think michaelwebster is right. The art world is a strange a ferocious one, if you have zero experience you will be eaten up. Take a few classes at a community college to at least get the terminology down and some critique experience. Talk to everyone you can who is a formally trained artist. Get real criticism on your work. You have to at least get your feet wet. Let me tell you, applying to grad school, and "making it" in the art world is arduous and emotionally-taxing even for someone who has gotten the proper training. Or if you really really want to go to grad school (as opposed to going on residency, or taking some time to focus on your work in general) you should apply to a new program that is looking for artists to get them started, or look to a program that is not prestigious but simply will give you studio space and instructors.
