I didn't go to college so I don't have any advice, but I moved out when I was 17, which was rough. So buy plenty of rice and pasta. It's cheap, and filling. And get toilet paper whenever you can. When I first moved out I would steal toilet paper from pizza places, certain gas stations, libraries. It wasn't right, but I was 17 and broke. Also, see if you qualify for food stamps, cash assistance, anything. Also check into food pantries in your area. I go once a month and it really does help. Also, water down your dish soap. You don't really need that much and it makes it last longer. There's definitely more, but now that I am an adult it turns out I still don't have any idea what I'm doing haha, so don't stress about that. We're all just trying to figure it out as we go along. Good luck 😁

Remember: everyone fakes adulting, there is no shame in asking for help, save money for rainy days
