I am sorry you are suffering so much with this problem. Like the others above, I would encourage you to see a psychiatrist about this. It sounds very distressing. You do sound like a good person who would be very unlikely to act on these inner promptings.

I've heard it said that people under the influence of hypnosis will not do things that strongly conflict with their moral beliefs. I suspect that is true of your situation also. It's not that people need to be protected from you, but you need to find a way to alleviate the pain you are experiencing.
