Try to keep on good terms with mum and dad, it may be in your best interests to stay at home until you can go off to university.
I would advise you if you are up to it to go to university, move out then and after university try to get a profession which allows you the money which you need to rent or buy a place of your own. This is just one way of getting out of your parents house.
I think that you need to think long and hard about how and when you are going to leave your parent's house, do not do anything rash like running away to live under a railway bridge or on a park bench.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
