Think long and hard about why you want to stay. Not why you should stay but why you want to. Then ask yourself if you will really get what you want by staying.
If you have prayed about it, and I assume you have, take a hard look at the answers you are getting. Don't let fear cloud your judgement when you do. It is very easy to ignore the answers because of fear of being wrong.
If the JWs told you about all kinds of good things that will happen to you by being a JW then ask yourself if any of them have come true. (sounds like you have been around them long enough to know)
