I'm going to be a bit less supportive than most of the just stay and save plan, not because I want to be mean or cause you anxiety, but because I don't see why you're having a problem. It sounds like you're just being immature and that having things like a room provided for you isn't forcing you to grow up at all. If you haven't saved enough to move out in 6-7 years, you're never going to. You're being coddled, you like being coddled, and until you move out and face the world on your own you aren't going to mature to the point where can improve your life.
So first, let's dismantle the idea that you can't afford to move out. Assuming full time, $11 * 2080 = $22880. CO tax will be somewhere around $1.1k, federal is about $1.4k after personal exemption and standard deduction. About $3.5k go to payroll taxes. You should have somewhere in the neighborhood of $17k per year or $1.4k per month. Not a lot of money, but nowhere near can't afford to move out level. Hard to save tons on this, but you should be able to live on it easily enough.
Savings - $140
Rent - $600
Utilities - $150
Food - $200
Bike - $ 0
Those are the big things, and that leaves $310 to pay for health care, have fun, take transit or own a car, or whatever else needs doing. Or save more like we'll all tell you to do. Assumptions are a low 10% savings rate and that you have a roommate. A quick scan of the Denver area (no idea where you are in CO) shows a number of 2 BR apartments in this price range within an hour bike ride of downtown, some of which are really nice looking. Some on light rail if you can't fathom biking. Totally doable and not in the ghetto. $200 a month on food for one person is easy, certainly not instant ramen-level. Fresh fruit and veg, some meat, a fair amount of staples, but good food.
Hopefully you have something to show for ~7 years of rent free life at home after high school. Use that for the security deposit on the apartment and the start of an emergency fund.
Once you're free and independent of your parents, make yourself two goals. First, a career goal. Go find out what an ideal job for you looks like that pays enough to save well. Could be retail manager, could be many things. Most jobs aren't exciting to others, but that's not the point of a job. Get paid so you can take care of yourself. Once you've figured out what an ideal job looks like, start applying to jobs that fit the criteria.
Second, a personal goal. What are you going to do to improve yourself? What's going to make you interesting and attractive to people? Having an apartment and a stable job isn't it. Are you going to draw? You say you want to make an anime. Maybe try your hand at manga first. The question is what do you want to do that will make you you?
