Hi WeatherLover welcome. Kudos for your courage in daring to take a look at what is out there on Jehovah's Witnesses. Congratulations on your future possibilities for freedom and health.Setting healthy boundaries with those you love can sometimes be very painful. You have to risk being real and risk rejection and risk the possibility of being the "persecutor/bad guy" in unhealthy triangulations. What you are experiencing as a young adult is normal and natural, the Will to be an individual who makes their own decisions and takes on responsibility for their life in their own hands. This is the opposite of the enmeshment many religious organizations and parents work so hard to keep their kids and members in.
Jehovah's Witness parents have an almost impossible time separating the difference between an adult child and a adult son/daughter. You're also dealing with wanting to go to college and possibly being LGBT, so that's quite a bit to deal and work with, but you're among friends who we support you :)
