That has not been my experience at all, I have met a lot of really great people since leaving. I did have some nice JW friends, but I also knew a few not so great JWs.
I would suggest you research the JWs a bit before you go back, there are a lot of things I was told by the Watchtower that were exaggerations and outright lines. It was quite a shock to me that in thirty years of being a JW I knew so little about them.
I was told the Watchtower predicted the last days would start in 1914, which is not true, they predicteded that Christ would return and the world would end, it was only when that didn't happen that they made up the bit about the "invisible return".
I also learned that that prediction was based on chronology taken from another religion and based on an incorrect date for the fall of Jerusalem. Now that it's obvious that their prediction that the generation alive in 1914 would not die before Armageddon was a failure, they have changed the meaning of "a generation" to mean a whole second group of people who knew the original group of people that were alive in 1914 would not die before Armageddon, this making up a meaning for the term "a generation" that is completely made up.
They have been secretly paying off victims of child sex abuse and demanding that the victims sign a nondisclosure agreement. They pretend they have very little child abuse in the congregations while maintaining a list of over 50k names of those accused. Pedophiles have been appointed elders even though they have been accused or confessed to abusing children. They recently settled a multi million dollar case, with more in the works.
In short, the Watchtower is not what it claims to be. If you are seeking good association, there are a lot better religions out there, not all "worldly people" are immoral or bad. You owe it to yourself to check things out, the truth is out there, but it's not in the Watchtower.
