Happy for you to PM me if you need assistance.
Speaking in a borg voice below (not my thoughts if you know what I mean):
If you work the elders and you get lucky - 6 months but they have 12mths minimum in their heads.
The name of the game is borg repentance - which is "looking guilty and miseable".
You have to be the victim.
You have to work it at the meetings and make sure you are seen attended.
Get an elder as a contact - see if you can score some shepherding calls they are not allowed to officially do them but if you get a good elder he will see you.
Always mentioned in your contact your spiritual routine. In your repentance rants it is all about how you have hurt Jehovah, and your family, and the cong and your friends. How Satan misled you, yadda yadda and how close you feel now. You never understood the sacrifice of Jesus like you do now...
When asked do not appear too happy - life must be hard so you can pay for your gross actions.
Tears are good too.
Having said that, all this is wasted if the main elder involved is a asshole. If you get a champion you will be fine. I used to have 2 other brothers and we would "get them back quickly". But sometimes if they were not involved I could not get it done quicker.
Hope that helps.
