Hi MsGrowingGirl. Not much I can add. Some great advise here. Maybe a little recap. Keep putting your education first. You won't regret that latter in life when you can get the good jobs. Plan you your escape wisely. You don't have to rush it but don't fall in to the enless cycle of pretending you believe it to avoid conflict. You can wind up wasting the rest of your life playing that game. Also realize (as others have said) the feelings of guilt and wanting to go back are all part of the this cults brainwashing. It runs deep and take time to get rid of. Check out the Cult mind control books mentioned here. It is easy to see the Watchtowers methods in them.
Best of luck. You are doing just fine.
