I'm not going to try answering that - at least not in the direct way you are asking your question, though I will circle back to an answer of sorts.
The primary reason that I won't - can't - attempt to answer it that my answer is mine. It doesn't apply to you. This primarily because I don't understand the context of the choices you're facing. Oh, I get the words. You can't explain it to me any more clearly. But you have found, as you put it, a place that "made you feel at home." This, I have no experience of. In any context. Also, you mention money to publish, which, as I read it, implies selfpublishing, which again is diametrically outside the scope of anything I could conceive.
So, coming back to your question - the deeper one: what should you do? Which choice should you make? You already know the answer that is right for you, even if you haven't found it yet. The real question you are asking (I believe) is: between these two aspects - the group that provides you existential support, and the JW membership that you see as a path to growth - which is more you?
Which option - assuming they are mutually exclusive - is more central, more fundamental, to who you intend to be a few years from now…?
Your answer to that question is the only one that matters.
