You know you are in the wrong religion when you cannot leave with your reputation intact.
My fading advice is stop going to meetings altogether. If and when the elders call explain honestly but secretively that you are dealing with a personal issue. The hidden personal issue of course is doubts about the GB/F&DS. Thank them for their interest and inform them that if you need their help you will let them know.
Keep what is personal, personal and do your research yourself without Watchtower lenses. This forum is a good place to investigate as well as Jwfacts.com
