Tips to moving out of your parents house?

Growing up, I have had a laundry list of problems with my parents. Reality is, I do not have a relationship with them and do not like being in their company. I am not sure if it is because there was so much conflict growing up as a child or the fact that we disagree on almost every level. Now eighteen, and attending the local community college I have decided that the only way to be happy is to leave my stressful home life and give myself some time to think and take care of myself. Having 4 jobs over the summer and quite a bit of money saved I am confident I am able to rent an apartment. But am worried I will not be able to last long. Me and a friend are looking at apartments near the college but are not really sure on a plan of action or how much living on our own is going to cost us. Recently, I paid my car insurance, but if I move out I’m sure I would possibly have to go on my own car insurance plan? Also my dad is co-signer of my car lease and they currently pay have of my lease each month. I go to the community college on a scholarship so I do not have to pay for school but daily expenses are inevitable. I am truly serious about leaving but am wondering what I need to expect and how much money I essentially need to get started on my own.
