Yes, I think I know what you mean. I struggle with similar demons. Do you know what yours are?

And I think you probably have noticed on this forum that many others fear their own dark sides as well. A thread I’ve seen recently refers to “my snake” or “my inner snake”. Posters have discussed various ways of dealing with this inner implacable enemy.

One classic technique which I am currently trying is simply to allow it to speak. Be aware of what it is saying and make note of it, but neither fight with it nor engage with it. There is a deeper part of you that will be able to do this without words, just awareness, which over time may lessen the power of these frightening thoughts over you. 🌹
