My mom actually kicked me out when I was 16, she said she had it with me, so I had to get a job as a roofer and support myself through that, so I have been living without my parents for almost 10 years. It was not the idea situation to be in, but it made me that much stronger. I am putting myself through college, and paying for a new car and house, but of course I got lucky and my wife makes very good money, and I do alright where I work.
With that aside, if I was you I would live under their roof for as long as you can until you can support yourself financially, because once your on your own, you will feel stress at a level that has not been known to you before.
