Freedom rocks, your situation is very familiar to all those of us who have left the JW cult. There is anxiety that all our precious foundational religious beliefs are being dispensed with and we are left with a void.
As JWs we were robbed! Robbed of our human right to know and understand according to factual evidence. Instead our whole life was the product of what we let the Watchtower impose on our minds and hearts as to what reality was. They were so very wrong-- and we were led up the garden path.
I think then that the first determination we should make is to be able to assess is whether a belief is based on a stories or based on fact and evidence. There are other things going on in our minds as we get rid of JW nonsense but from the point of getting a proper grip on reality we have to start somewhere and this is it.
Understand what is "belief" and what is testable fact and be ruthless about it. Understand the difference.
For example although many people have forever believed in a spirit world there is no concrete evidence for things which are invisible and cannot be measured in any way. Their existence is only in people's minds as the result of wishing to believe.This is the essence of belief.
Humans are however not logic machines we have a strong emotional component, it created our many cultures and is drawn from our earliest experiences in life, the warmth and security of being cared for as an infant. . . but don't get snagged in this mode because the normal human grows up (not JWs!) and works things out for him or herself.
As we work things out after JW life we must ask a new set of questions. Not "Does the religion approve?" but "Is this or that idea based on solid evidence?". Evolution for example is based on solid evidence but if you live in the United States there exists a movement to stem the loss of Biblical authority and is creating its own defensive culture to support the indefensible claim that God created the world. Look at the evidence. You looked at the internet and heard "others" said there were arguments against evolution. Look at the evidence for yourself.
