You're haunted by intrusive thoughts

These thoughts are frightening precisely because you are a good person recoiling from them — and understanding them removes much of their power. First, a thought is not a wish or a deed; it is an event in the mind, and the mind throws up all manner of images, including the very things you would never do, so their appearing says nothing about your character. Your horror at them is proof of the opposite. Second, fighting the thought is what gives it power — the struggle marks it as dangerous, so let it be there as the meaningless mental noise it is, neither pushing nor engaging. Third, drop the rituals that promise relief but feed the fear. This is hard work, and when intrusive thoughts rule your life, a good doctor trained in exactly this helps greatly.
