James, nice to meet you. Please take my opinion here seriously or not, my motive is to give you something to think about, not something to believe in. But, I have the very best of intentions with my limited perspective.....
I saw you were an elder and likely were overworked, very busy, and probably saw one or two unpleasant things on JC's through the years. The only way any elder can sincerely justify this activity is through "belief", and that they have a mission, a purpose, and thus, soldier on. That is why you will likely meet with some resistence regarding the value of trying to find a new "belief" to replace the old one.
Be patient. Take some time. It's ok, and you're ok. The doubt and the vacuum you are experiencing is normal and to be expected.
May I suggest that what you really need is to fill the purpose and the mission that you had? That in of itself is very honorable, and while it likely does entail having a belief system of sorts, I would start with purpose, as opposed to beliefs. What are you good at? What difference can you make in YOUR world? Start small, start organically, and let it grow naturally. Discover what and who you are now without the polyester clothing of JW dogma, and that will turn into something good.
This is totally just one mans opinion, but I strongly believe that exiting JW's who were pioneers, MS, Elders, and up are/were very mission oriented, and caught a very specific kind of narcissistic virus that JW leadership spreads. It's the idea that YOU can really make a difference and change the entire WORLD, and be on par with Abraham, Moses, David, the 12 Apostles, Paul the @$$hole, etc.
And then you leave, realizing how small you are, maybe not as powerful, but most certainly not powerless.
You are not powerless. Find out who you are, love yourself, love your family, and the rest will take care of itself. But be patient. It does take time. :)
