Hey I also sent you a message but in case you don't get it,
I told my parents when I was 15 that I didn't want to be a JW anymore, my dad beat the crap out of me MANY times, like you I also felt like I might as well end it all, but, what my parents did was take everything away from me, no lunch money, no more clothes, no personal items ( hairspray, toothpaste, etc.) My dad said roof over my head, and dinner thats it. So what did I do, well I got a job, worked nights after school, weekends and summer time. Anything to get paid, Anyway I ended up being able to leave my house at 17 I almost joined the Navy but I got my own apartment, and life turned out really good for me. There are many of us here that have gone through what you are going through.
PS I am sorry your in homeschool, I hate that about JW I fought my parents not to do that to me, I am so glad I won, but I also met a bunch of new friends working my side jobs, I wish you the best of luck and we are all here for you if you need a bunch of crazy ass friends :-)
Take care,
Andre
