I experienced similar things growing up in this cult @ the same age as you. It is a very lonely place. The only thing that saved me was meeting my best friend and mate in life early on. Keep focused on your education. Education is what will allow you to go on your own and rely on yourself. Three years will go by quickly. Rely and trust in yourself. You can do ANYTHING you set your mind too. Play the game to get your education and once you do, move on and take care of yourself.
I know this sounds selfish but take care of yourself. NO ONE else will do that for you.
