I feel for you. Do you have minor children at home? If you become a dub again, be sure to provide them with some activity that is not depressing or hopeless, and help them to understand that "worldly" people are good people, but with different beliefs.
Letting go was one of the hardest thing I ever did. I resisted, but after about 2 years, everything came together, and I was mentally free as well as free in any other way.
Make a list of pros and cons. Talk with a psychologist, especially on what to teach your children if there are any.
If you do go back, try to move to another town where the JW's don't know you. Miss as many meetings as you can. Find excuses to get away and be with other people. Find the meetup group in your town and keep in touch with ex-JW's for support.
Remember that even if you do go back, you can still change your mind. Learn ways to cope with depression and despondency.
Best wishes with your decision.
