any religious people having a tough time?

i’m a Christian, and instead of dealing with reasonable questions in a healthy manner, i’m instead constantly flooded with ruminating cycles. i cannot just look at the information presented before me and make a logical decision. instead my brain automatically resorts to whatever the scariest answer is and assumes it’s true because it is the most frightening.

i wanted to know if anybody else deals with something similar, and how they’ve been able to break the cycle so they can sort their thoughts in a constructive way. thanks!
