I’m getting kicked out at 18

My mom is kicking me out at 18 after I graduate because she won’t get child support. I’m turning 16 in two weeks and I will be getting an old car.

I don’t know what to do to prepare. I want to get a four year degree, I am at the top of my class right now. I will get a job when I turn 16 but I know I won’t make a ton and I will also need stuff. Any advice on how to save and prepare? Two years isn’t that long.

Really not happy because I have literally never been in trouble and make good grades.
