So you abandon your former beliefs for what ? Spiritual darknes because you have left the 'light of truth' and have found nothing else, not even new beliefs, not even a new conversion. Is this really smart? To leave something for a nothing is just plain done and shows the state of your intellectual character and faith. You do not deal with doubt by abandoning such doubts but use those doubts as stepping stones to greater wisdom and understanding as found in God's Word and revealed by the Faithful and Discreet Salve and Holy Spirit.
I left the wts because I found out that the "something", by which I assume you mean the org, was really nothing. You will no doubt disagree, but I realised that I had been duped. The watchtower do not have the truth, or anything resembling it, and neither you nor the circular reasoning you employ on this discussion board will convince me they have.
As for having found nothing else, I haven't looked, and I won't be looking. I no longer have any faith in either the bible or God. I would describe myself currently as an agnostic with leanings more towards atheism than belief.
You may wonder what led me to reach the conclusion that the wts do not have the truth. Well, it was a number of things, the wts handling, or, I should say, mishandling of child abuse cases, the wts involvement in the UN, the cruel and inhuman practice of shunning and the lack of genuine love in the congregation were the main ones, as well as the information I read in Crisis of Conscience.
I am not ashamed of my current non - spiritual state, because I have done nothing to be ashamed of. Since leaving, I have found what happiness and freedom really mean. I now live with my ex jw boyfriend, who has been more of a friend to me than all the jws I have known put together. I have left the lies and hypocrisy of the wts behind me, and I will never return to it. That really would be a case of a dog returning to it's own vomit.
