You should find an AS or autism support group, if your area has one. And then explain your differences to the people at the group. You may get some help in that manner.
I'm thinking about moving myself, but not for the same reasons. My parents aren't bad people, just too overwhelming at times. My parents know that I want to move, because I've bluntly mentioned it upon numerous occasions. I just find it hard to discuss the reasons why in any emotional context, because I don't like personal discussions. And my father isn't exactly wild about the idea of me living on my own, which just adds to the overwhelming feeling, so when I do it, I just may end up leaving with a note attached. But, I won't do it unless I have a decent job.
I'm not sure if you're able to sustain work, but AS and autism are considered disabilities. You could get help from organizations specailizing in supported employment, personal planning and so forth. Again, I don't know what exists around where you live.
