It is difficult, but I bet that deep down, you know you will have to find a way out of the Watchtower. As a teen, you need to take your time and figure this out carefully. But as a teen, you may think that years are an awfully long time.
At some point, you will have to face a loss. Try to make it a loss of JW friends and not JW family. Ditch the fake friends at some point and start developing real friends. Consider your career future to be way more important than your JW or former JW future and make goals.
You will figure it out.
