So sorry that you are getting treated poorly. One of the main reasons our entire immediate family left this crazy cult. The lack of love is just incredible.
If you are attractive, have a good personality and are seeking to get a higher education, they will come after you with a vengence or ignore you completely. You see...they think they are better than you. This will not get better. I will be very blunt here, run like hell. I wanted to leave this cult at 14 years old and wish that I had never been born into it. There are good people within in but the majority would love to see you fail and fail miserably. I had one sister (well several) treat me the same way. Best advise...RUN!
If these are the people I will have to live with in paradise, I will enjoy my life now and take my chances. Nothing is worth getting treated like dirt.
Keep on seeking that education, take good care of yourself live a happy and successful life. That's the best revenge!
