Isn't it awful that when someone needs help the most they get treated the worst by witnesses.
A religion that must tear you down and make you miserable in order for you to "come back" is not a religion, it's a cult.
I'm truly sorry you're going through this. Just remember that there are a lot of other people out there who know what you're going through and how tough it is. Feel free to vent here anytime.
Another poster recommended making new friends. That sounds like a great idea.
I know you're disfellowshipped but I don't know how much of the witness teachings you reject or accept. So, if you have any lingering doubts about the WT being right you should read Crisis of Conscience by Ray Franz and you could do research on points that have bothered you in the past.
Sometimes the pain of being shunned can be eased by knowing for certain that the shunners are wrong in their beliefs and wrong for shunning you. It isn't Christlike to shun.
Good luck and I wish you the best.
