This is an interesting thread. There are lots of conflicts like this in my family, since on one side we're somewhat too familiar (in terms of living in close proximity to one another) for our own good. I got out of it for a while when living in Oregon, but spent too much time back in California since I majorly injured myself back in February of this year (adding at least an extra 6 months onto my plans), which put me out of the job market pretty much for good. It was hard to move on in such a state, and it still is a daily struggle, but I somehow ended up a good three states to the east of anyone I know, and now when I come back to visit it is with an understanding that I will come and go as I please, and can handle myself just fine when push comes to shove. It just takes me a little longer now is all.
I think Heorhij's idea of school is a good one. No one in family is really of the book learnin' variety (I'm the first one to have graduated from an actual four year university on my father's side of the family), but my older brother managed to go to a technical school in Laramie, Wyoming when he was around the OP's age, got out in two years with a wife (now ex-wife...oops) and a pretty steady job selling auto parts. It wasn't quite what he wanted to do, so about 6 or 7 years ago he joined the family business (rock'n'roll) and is now a drum technician for one of those 70s/80s nostalgia acts, gets to travel the world (he's in Ireland for the next week or two) and is having the time of his life. And God bless him for it. I have done pretty much the exact opposite by going into academia, but it's what I want and I like the idea of not following in others' footsteps. I know it's gonna sound like an after school special or something, but even if your parents needle you about never leaving (my father did, and that was while I was in traction; it was a bit like living with Don Rickles or something), don't internalize it, and really keep your eyes on what you
want do with your life. Because it is your life, not theirs, but to make it all happen it might behoove you to start thinking of autonomy as more than setting your own bedtime.
If your parents are anything like mine, they will start respecting you a lot more when you show that you can put your mind to some concrete, long-range goal and do everything you can to meet it (not that you have to have your whole life planned out at 22, but give some indication that you're really thinking about your future). And you'll probably start feeling a lot better about yourself, too. Good things will then follow, God willing.
