To go back because you think these bad things have happened to you since you left the organization is to say God is punishing you and also sort of egotistical. If God is truly punishing you, don't you think he'd be even angrier if you go back under false pretenses?
Bad things like this happen to good JW's too. I know a wonderful guy who is the father of 5 kids. He lives for the "TRUTH" in the space of 2 years, he lost his job, had his house repossed and died during surgery for some rare heart defect. He couldn't take Blood and they gave him a 10% chance of surviving with blood and a 1 percent chance without blood. He basically said goodbye to his wife and kids when they wheeled him in to surgery. I know so many cases like this. His wife and kids live in a crummy little rental house because the only job she could get was in a fabric store.
I left the Org and my life was instantly better but I was waiting for the axe to fall. Wasn't Satan supposed to be lying in wait for me? Then a few months later I got the best job of my life..."But wait" I said to myself "Maybe Satan is helping me now that I'm supposedly on his side" Then I realized that my JW training had set me up in two ways. If I leave and do well....it's Satan but if I leave and do badly It's Satan double crossing me and God punishing me.
If you go back, do it for the right reasons, not because you are superstitious.
