KK123, you will easily qualify for FAFSA (loans), grants etc. Financial aid and affordability shouldn't be an issue to you. In fact, you will even get money to go community colleges if your income is as low as you told us. 

Since your academic qualifications aren't that good, you will be struggling in the long run, provided that your priority is to make money or living in the US long-term. At least get a Bachelor's. You can always take vocational courses like Mechanics training etc but to hold a decent paying job, you need skills and meet up basic requirements. You won't make decent money by working in Gas Stations/Liquor stores, even if you worked in one for 20 years. 

I'd strongly urge you to go to a community college and speak to the financial counselor. Start off by taking some 6-9 credits in your first semester but remain focussed on graduating college. You can also do part time job. 

Also, try finding jobs in non-traditional places. Non-traditional jobs meaning outside common workplaces(i.e. Gas Stations, Liquor stores and Indian Restaurants). Talk to your customers and start networking. Who knows, maybe one of them works in a bar and will hire you as a barback, eventually paving the way for you to become a bartender? 

In any case, keep focussed and push yourself to getting an academic degree. 

Good luck!
