My Struggle With Christianity

I (20f) was raised in an agnostic/atheistic home. There was no church, no scripture, and no religious values. When I was around 10 years old, I developed a deep yearning for religion, specifically Christianity. Since then, I have done EVERYTHING possible to become a Christian, but I’m stuck. I read the Bible daily, I pray, I try to only consume Christian media. The issue is that I just don’t believe the Bible. I have read the entire NT and a large portion of the OT, but when I read it, it feels like I am reading pure fiction. How on Earth can someone read the Bible and absorb it as if it’s 100% truth? I can understand someone being able to believe it if they were raised in a strict religious setting and were taught to believe, but I don’t understand how anyone else can do it. I have heard a lot of people say that belief is a choice, but if that were true I would already be a believer. I’m guess I’m just afraid that my upbringing has destroyed my ability to have hope and believe in the Bible.
