You have gotten some great advice here, but I have to address something. A bunch of people have told you not to get baptized because then the church will have power over you. That is bunk. It just isn't true.
Baptism is a verbal contract at best and one they cannot possibly enforce. Can you imagine if you went to court over breach of contract? They have never ever even tried to do that to someone, because they don't have a leg to stand on. They have power over you only if you give them that power. The better reason not to get baptized is if you don't believe in the religion or in God.
No one should tell you if or when to get baptized. That is a personal choice between you and God. No one else gets any say in it. It isn't a contract between you and the religion even if they say that is what it is. it isn't a legal contract and the only power it has as a contract is if you believe in it.
For me, getting baptized was what brought me out of the JW. That was the beginning of the end for me. I didn't get baptized for them and it was that moment that I realized they had no power over me. Leaving physically and emotionally wasn't as easy as recognizing they had no power over me. I was still underage. I do not, for one moment, regret getting baptized.
