How do I know what's true?

I want to believe that Jesus is God and the Bible is true but what if I'm wrong? What if the only reason I believe in Christianity is because its what I was raised to believe? How do I know Islam isn't the true religion? How do I know what the Bible says is true and Jesus really is God and died and rose again? I've been trying to learn more about Christianity and Islam and I don't know what to believe. Muslims say the Bible has been changed and I understand why they say that bc there are so many different translations. At the same time though all the translations say the same thing just with different wording. Also I heard a lot of Christians are converting to Islam so why is that happening? There's also a lot of Muslims converting to Christianity but when I see videos about that the comments just say they're wrong and confused. I'm confused. How do I know what's true? Whenever I see someone say Jesus isn't God and you're going to hell if you believe that I get this feeling of fear and I'm like "what if I'm wrong and I'm going to hell?" it's uncomfortable to say the least
