urgent!! moving out in high school

Heather
I'm moving out of my parents house before I'm done high school. I need Advice and help on how to budget and what I'm going to need for necessities. Basically anything you can tell me would help, I'm 17 and finishing grade eleven right now, and I'm moving out in 4 months, I'm finishing high school a semester early. My current monthly paycheck is 700$ per month and rent is 500$ not including utility bills
