My family did the same thing to me (except they didn't hit me.)
When I wanted to move out as an adult my mother took to her bed crying & my father called me up and said I was as cold as ice and cared about nobody but myself. So I stayed G - U - I - L - T
When I finally left it was the best thing that had happened to me.
Get a book called "Toxic Parents". It is AWESOME and helped me a lot. I can't remember the author but if you go to Amazon.com and search for that title you will find it.
Also, to help you get past the "OMG what if they are right Armageddon is coming and I'm displeasing JHVH" phase, start reading and educating yourself about this so-called religion. Have you read "Crisis of Conscience" by Ray Franz, a former GB member?
At www.freeminds.org there are tons of good books.... like "30 years a Watchtower Slave" among other goodies. Get your hands on a couple of those (have them sent to your significant others' house so you don't set them off again.)
You need to GET OUT as soon as possibly can.
BY THE WAY I'm from NYC, born and raised, and it's NOT filthy and disgusting (LOL) and I've never been raped!
