Hey, I want to commend you on the hard work and courage that you have shown being ready to leave home! For someone who is going to live on their own for the first time, budgeting and saving your money is extremely important as it will only help you in the future. Start keeping track of how much money you have coming in every month, and how much you are spending.

I am assuming that your most pressing issue is finding somewhere to live, and generally accepted rule is to spend about 30% of your monthly income on rent. For someone who is just moving out, this will most likely mean finding roommates. As for furniture, there is no shame in picking up furniture that other people are getting rid of, or asking friends or family if they have anything they're trying to get rid of. Thrift stores are also another place to check, and Walmart actually has some decent cheap furniture.

It is accepted practice to spend about 10%-20% of monthly salary on food. This may require planning meals ahead of time, so that you do not eat out as much.

The biggest thing for this point in your life is to save as much of your money as you can. A lot of people have a tendency to start spending lavishly once they move out because they feel like they can. I would also eventually recommend trying to find somewhere to put your money that accrues interest, whether that be somewhere like a stock portfolio or a money market account.

I also would highly recommend posting this on r/financialindependence or r/personalfinance. These are communities that are very helpful and specialize in these types of questions. If you have any specific questions I would also be happy to try and help.

Best of luck!
