There's not a ton that I can do to help. There's no magic bullet that I have. No great answer I'm sitting on that I haven't shared.
But I'm not speechless. I can share my own story. I can express solidarity. I can suggest things to read if there's a particular theological perspective that I think might be helpful. And sometimes I offer this response:
Have you given Christianity a try?
A lot of "faith struggles" are purely mental events. Wheels turning in the mind. Which is fine, but much of that mental drama has little to do with being or not being a Christian. I'm not saying that our questions aren't important. I'm saying that getting mentally okay with Christianity still doesn't make you a Christian. There's more to it than that. Like actually being a Christian.
Let me say it this way. We routinely say that Christianity isn't about intellectual assent to propositions. Christianity isn't about believing all the right things, checking all the right theological boxes. But if that's the case we have to say the same thing about our doubts.
Being or not being a Christian isn't about all the mental drama, all the stuff floating around in your head.
If orthodoxy isn't all that important than neither are your doubts.
