Call your aunt now and tell her what is going on. Keep her in the loop with everything that happens in your life. See if she is ready to take you in. Have you gotten a part time job yet? Are you driving? And yes get in a real highschool!! Are you allowed to make this decision on your own? If you live at your aunt's, you could join drama, clubs, go to prom. But you also lose your parents. Makes me so angry and sad.
It's always Satan Satan Satan! It can't be that they're in a freaking cult, can it?
