Alright, thank you very much for the replies!
Making the spreadsheet is part of forming a budget. I'll take any tips I can get honestly

Typically rent is 300-400 where I live (For 1-2 bedroom apartments), but for me taxes would only add up to $150. I'm used to not having a lot of money and have always known how to buy things on the cheap. I think creating a budget will help me stick to that. I'm not going to say it's not scary, but I am trying to deal with a lot of the things that could cause problems before I take a chance. So far buying my own food has fit into my spreadsheets and stayed under my income (Even when I add in taxes, utilities, and other necessities).
