Mentally preparing myself for homelessness

I'm a 19y f and I'm going to have to spend this summer homeless. I'm a college student and I have nowhere to go for the summer once school ends since I can't afford housing in the area I'm staying in even with a job. I have a car so I'm not going to have to sleep outside thankfully. I've never had to experience homelessness before so I don't know how to approach this situation.
