Family issues are one thing, but the 'God thing' is another. That description indicates where I am now, but I think I had a rather relaxed journey from a point, not so long before I started my journey out, where I spent a whole day in fervent prayer telling Yahweh and Jesus how much I loved them both, on to a point where I could be described as an atheist.
Do you really think it matters a lot whether you believe (and talk to) a personage whose existence we can only attempt to imagine? OR, whether we do not believe in such a personage?
Even when I was a mentally out and got the big pork chop award, I was still a believer. I suggest our journey from there should be gradual and relaxed.
It will not make a skerrick of difference in your ordinary everyday life, whether you believe in a divinity or not. As you may observe, the lives of unbelievers is not much different to that of believers. Good things happen to both and sometimes bad things.
I say all the above while acknowledging that I get a bit of fun out of ridiculing the supposed existence of some super-human divinity with supposed super powers, but who never deigns to demonstrate them to us.
Just relax and have an interesting trip to wherever you finish up - grin.
