Hi Ozze
God if you only new how much I can relate. First of all, I have what you have involving violent images and thoughts. However, they involve killing myself not others. I think these thoughts all day almost every second and I know your pain. It has been the most awful 6 months of my life and I have such a hard time determining what is reality and what is not.
What you and I have is a form of OCD called Pure-obsessions. There are 7 kinds of OCD and this is the most difficult to conquer because it involves no compusions. We do not want to act on these thoughts but they do not go away.
It does not mean you are a bad person..you have a disease called OCD and like me you need a lot of support. Write to me whenever I can offer help. I know a lot about it.
