I will pick up your question, Why are we here if we no longer follow the JW religion?
Largely because we want to share our experiences with newcomers like you and maybe help you stop yourself from making the same mistakes that we did.
With me, I did not suffer at home as some have but I did experience the crushing disappointment of realising that the beliefs that I had molded my life around - were just not true!
Having been taught to expect a brand New World imminently, back in my childhood, I am now in my eighth decade and still it is awaited. Such expectations go back to the nineteenth century, without fulfilment.
I could no longer stomach a teaching that all non JWs , old or young, good bad or indifferent by normal standards will horribly slaughtered at Armageddon, by our “ God of love”
If you can accept and find joy in such things , then feel free to continue your study but please consider all the other information that is available about this organisation, before committing yourself.
