You will regret if you try going back. Going through all the hoops as some have done just isn't worth it. If your friends actually shun you then what are the chances they won't go tell elders the first chance they sense you are spreading "apostate teachings"? If you have a good friend, call him up and talk to him, tell him what you think he should know so he can check his references, you can do likewise with whoever.
I thought I had a good friend too, we talked about anything and everything until the day I told him to read old WTS publications and that I am leaving the WTS. Well, that was the end of that "friendship," since according to him we had nothing in common. I don't regret leaving and have no use for the dubs who shun others. My inlaws still talk to me while they know I HATE WTS with a passion. Sometimes we make ourselves believe that we need to stay away from jw "friends and family" as if it's our own duty to do so. If you want to know if your friend(s) are real or false, call them up and talk to them . Don't waste any more of your life by going back to be pushed around by elders so they can decide if you can be reinstated after 6 months or 2 years.
