**i just dont like them...and dont like thinkin this stuff.**
I have a similar problem. I haven't visited this forum for a while, as I didn't want to admit to myself I still having these thoughts. I've tried to ignore them, but they've been getting worse and worse. Like you, I am not remotely violent and I know these thoughts are not "real", but they still scare me to death that they are in my head, I don't know where they came from and desperately want them to go. I have no peace from them. I feel frightened of them, and the sense of anxiety and guilt is crushing. I am cheered by other people here who have broken the vicious circle and hope you and I can break ours, too. I have noticed they are worse after a night of a lot of alcohol, but that's the only thing that gets them out of my head for a while.
You are not alone. Take care.
