What the emperor sez: You're smart, you've figured this out young.
Might I add that it is a false dichotomy that you only have two choices: Either I have to keep pretending to support an organization that has caused so much pain to so many people, or I have to abandon my family and friends to it so I can save myself. There are many gradients in between those two polar opposites. You're smart. You're young, you can figure the rest of this out. Your situation is like no one else's and yet, it's like all of our own experiences. Take the advice here that helps you. Leave the rest. We're all supportive. Think of your many alternate paths out...and yes, get that education. You're smart. You've figured this out young.
