Lostfromthefaith, I understand the spiritual quest you are on. The desire for a deep relationship with God. No one can tell you what is right for you, the journey must be your own. Do your research. Ask questions and if the answers don't feel right, ask more questions. One thing for sure is no one has all the answers. No matter what a particular religion claims, they truly don't know it all.
As far as JWs are concerned, their teachings appear to be all bible based, and most of them are really good people. Just keep in mind that they discourage higher education, association with others outside of the organization...including your parents...is really discouraged and although not forbidden, you would never be permitted to celebrate another holiday or birthday, you could never participate in any school activity or be friends with people you go to school with, and most likely since you weren't raised "in the truth", the kids at the hall would not be permitted to closely associated with you.
It's really great that your parents are supportive in this, so get their advise and opinions. They only want what's best for you and they would have a more experienced outlook to keep you out of a potentially harmful situation.
