This happened to me a couple of times last year, when I was 17. Packed everything and left home (both times school sent me back home)
I'm not here to tell my life story, but just to tell you something that was said to me when I ran away:
"you're only swapping one set of problems for another"
As much as I hated to admit it at the time. It was true. Now I still don't get on with my mom well, but in some ways, it provides me with much more motivation to work towards uni, so I can get out of here.
And things get better between you and the parents as you move away, grow up, learns to support yourself and start to face the problems they do.
On a less serious note, if you are one of those people who swear blind to NEVER be anything like their parents (comme moi), then never listen to anything they say lol. Once you do this, you will start to see things from their perspective hence opening the door to the possibility of thinking/acting like them towards something.
