It also depends on how well you can stand being dishonest. For me, at one point before my fade, I started realizing I was not going out in service. I remember falsifying my hours on my monthly report. If you are meeting the national average the elders should be satisfied because you are not dragging the congregation average down.
Next, I highly recommend making friends and strong ties with non-Witnesses. For me it was co-workers. I ended up getting a job at a place some of my non-Witness college classmates worked at.
Finally, at some point switch congregations. Probably somewhere far from where you live. Attend a few meetings at a congregation that is probably going to end up being merged and lose their Kingdom Hall to a Watchtower sale. Once your publisher records are sent over, vanish. Don't tell anyone in the new congregation where you live or what your telephone number is. Once you switch congregations you are no longer a liability to your current body of elders.
You have to be honest with yourself. At some point you have to decide - am I in or am I out. You will lose every Witness friend you have. Be sure to have built a social safety net with new friends before then.
