Me then- militant atheist. I could not find help that wasn't infused with superstitious BS.
Me after putting down the needle and bottle- non-theist AAer and CBT-proponent. As time goes by, I am more and more able to to just BE and be okay in my own skin. I also need to quit fighting everything and everyone. I highly recommend
In the Realm of Hungry Ghosts by Gabor Mate. It was transformative for me.
Unfortunately, the extinction of religion will not happen in my lifetime. So I have to adjust my perceptions so I can remain godless and happy, joyous and free. And there are a lot of us.
