Welcome. It's quite common for people to be affected by this religion even years after leaving. It might help to read about cults, even if you do not believe it's a cult. The tactics they use are why it is still affecting you. Read howcultswork.com, it's only a few pages, it's not about JWs specifically, but I think you will find that this religion fits all the criteria. Even if you still want to believe some of what they teach, it's good to recognize the manipulations when you see it.
Yes, some people here can get a bit crazy, but I prefer that to the rigid conformity of the Watchtower. Just skim over the offensive posts.
Again, a warm welcome, I hope you find friendship and healing here.
