Join the military.
You will be independent from your family and will receive a paycheck. If you have any student loans, you will be eligible for deferment while you serve.
With a degree, you may be able to serve as an officer.
You will attain the best physical condition of your life, and all your survival needs will be met: housing, food, work clothing, medical and dental and vision care, and work transportation. You will learn an employable skill, and you will be serving your country. When your enlistment is up, you may have a better idea of what you'd like to do... If so, the GI Bill will pay for whatever additional education you decide to pursue, and any previous student loans will be eligible for deferment while you attend school... AND you will have veterans hiring preference at many employers.
Or, you may decide to make the military your career, in which case you can retire young and draw a military pension for the rest of your life, possibly while you pursue that education and/or second career.
