I am going to weigh in with my personal experience too, just avoid and ignore (shun) them. I know it seems that they are at your heels right now and you want to be left alone, but if you take the initiative to shun them and do not answer the phone or the door when elders call, trust me...they will eventually quit- some other "problem" in the congregation will come up that needs "judicial action", the elders will have someone else to bother. Plus I think the elder body as a whole has a form of ADD, another "shiny" object comes along to distract them and they forget all about you.
For the first year I was out, I got the most pressure from friends and elders when it was time for the CO visit...that is when the CO would go through the files and find out who is inactive and put a bug in the elder's bonnet to "encourage" me...but shortly after the time of the CO visit the elders would go back to dealing with the host of other problem children in the congregation and forget all about me again. Now I moved to another territory and all my "friends" in the hall have long forgotten about me...they moved on to other "shiny" objects and made new "friends", they dont call me and I dont initiate contact with them.
I know you have friends that you have known your whole life and you feel an obligation to them...but sometimes you just have to let them go. You can still love them and wish the best for them (wish that they would get out of the cult too), but they have to make their own life decisions....if it stresses you out too much to keep in contact with a "conditional friendship" that just let it go.
I'm sorry you are going through this, I remember how stressed out I would get too (I also bit my fingernails)...but trust me it will pass in time.
