For CODA people, I'm a fan of 12 step but lately I'm having trouble with the God/higher power stuff and could use some advice

So I'm attempting to once again do some CODA work. My beliefs have varied over the years but I could always somehow make it work in my head/heart to do the work with regards to higher power etc, but I've lost faith in nearly everything in the last few years and I'm having a really hard time figuring it out now. And especially with the sometimes more religious phrasing(currently reading the blue book). I don't understand how to put my trust in something else when the feeling of being let down by everyone/everything is kind of the biggest thing I'm trying to work through.

I know this isn't an uncommon feeling and I know there are a lot of CODA people who think of it in all different ways. Any advice from personal experience?
