Lo-ru and Toby
Welcome to the site!
Personally I perhaps have had it differently. I left about 3 years ago, and felt guilty as hell for ages, until I found this site and went onto read Crisis of Conscience. After that I was fine, I made my decision never to go back. Although like others already on this thread it may take you more time, but you could be like me. Suddenly everything 'clicks' and you can get on with your life, free of the JW's.
Good luck
