Money

So I’m essentially getting kicked out and I have to pay for everything myself which I’ve already had to do. My sister is a drug addicted and my parents pour all their money into her rehabs which never work, and we constantly have to move because of expenses. I’m going out on my own and I’m 17 and working but I need extra money to finish buying my car and setting up my insurance. I also pay my phone bill and transportation and gas and for classes and food and rent etc. any food suggestions on how to make extra money ASAP? I need this so badly, anything helps, thank you
