Ok, Maybe the vegetarian example wasn't the best. I stopped drinking once and wasn't cool enough to hang out with my friends, quit drugs, and couldn't even talk to my old buddies.
In both cases, the relationships you formed centered around unhealthy addictions. Once you got help for your addictions, you no longer had a reason for those relationships. And since your friends no longer had a reason for you, the relationships ended. Either way, this wasn't a form of institutionalized shunning so much as it was a case of moving on.
And that's what we're talking about here -- institutionalized shunning. You seem smart enough to know the difference.
Got tattoo's and had friends not want to be seen with me. Left home to college and parents decided not to be a part of my life.
Not to play the pop psychologist, but I'm beginning to sense that you have issues, a hole in yourself to fill, etc. You've turned to drink and drugs, you've mutilated (decorated -- I don't mean to invoke a pejorative) your body, and you have problems with your parents. Now you seem to be leaning heavily toward joining a cult -- and yes, it is a cult. Something's up with you.
Maybe I'm just numb to the whole shunning thing. Since everyone seems to shun everyone at some point in time, however this Jw was at least honest in telling me it would happen.
The reason you're numb to the shunning thing is that you've put yourself in abusive situations with abusive people so many times, it seems normal to you. Healthy, normal relationships do not invariably end with hatred, intolerance, and shunning. The fact that you're considering a religion known for its harsh shunning practices only convinces me further that you've fallen into a rut and need help.
It seems to hurt more when you don't know.
This is very sad, but I hope you can at least see that there is a difference between institutionalized shunning, in which people shun you without knowing why they're shunning you, and the personal termination of relationships, which are made by individuals for their own specific reason.
Good luck, anyway.
