Hello Scarlett,
Dissociating from the teachings of a group such as the JWs isn't easy. If at times, you feel confused about the righteousness of your decision to leave, focus on the core reasons that lead you to leave in the first place. Don't ever ignore these by focusing on what appears to be good about the group.
While you are still close to your parents, the reality is that you need to go forth and build a new life, where, perhaps, you will be a parent yourself. This doesn't mean it will be easy, but it will certainly be easier than staying in a group that will not let you be the best of what you can be.
You're still young and you could be surprised to know where you'll be. Not dedicating 20 hours a week to a religion means that you could dedicate that time and energy to other things that drives you. You'll discover new horizons and find out options you weren't aware of their existence.
