It's kind of like magic spells. If you believe they work, then they will but if you do not believe in spells they will not work. So, stop believing that the jws have power over your life. Bad things will happen to you if you're in the organisation or not. Being in the jws just distract you and give you false hope. That is why it seems that life was so much better inside the religion, because you were kept distracted by the carrot dangling in front of your face.
You shouldn't go back, because religion will never make you or your life better. It is you and you alone that will do all of the work to create a happy and successful life for yourself.
You should not go back because the congregation does not have a genuine interest in you, it is a waste of time reading pages of literature. You could take a yoga class or study something that will actually help you. You will lose a lot of money spending on keeping up appearances, fueling the car, donating to the organization. They view you as weak for leaving in the first place.
THEY DO NOT CARE ABOUT YOU, ONLY THEMSELVES.
