This sounds like racing thoughts. No matter how much you want to stop racing thoughts you cannot. I think you could try a nice long hot bath. We can have scary and evil thoughts but we don't have to nest in them. What helps me is to praise God, praise God, over and over again until they are gone. You are not to blame for these feelings and thoughts so don't punish yourself for them, but you don't have to accept them as yours. Just keep praising God over and over which is objective thinking and don't let these thoughts stay with you. I might add we are humans but we are still flesh akin to animals there is that side of us the animal side I mean.
