If someone is losing their mind, do they realize it? Or someone who a psychopath know they are?my head feels so foggy and I'm emotionally numb I'm scared I'm these horrible thoughts. I can't take this

Hello, I think you might be looking for reassurance here to lower the distress of your instrusive thoughts. Not your fault - but it helps us identify what is going on here? Are you currently working with a therapist to tackle the obsessions and compulsions?

Lots of people who develop severe mental illness have very low levels of insight; self awareness is actually more rare. Also perfectly possible that a psychopath won't know for sure that they are one, especially as they don't have an experience of emotions to compare their lack of emotions to. They might assume that everybody is just acting like they feel things and that nobody really has physical sensations of emotions. I can understand why the idea that you could be going crazy or be a psychopath is frightening. But it can't be frightening forever if you don't feed it, just like a funny joke isn't funny the 100th time. If you can ruminate less, by noticing when you're trying to work this out/weigh up evidence, and choosing to instead do something beneficial and healthy with your time, even though it feels unsteady and negligent to do so, then over time, ignoring the questions will become your new habit. Treatment for OCD doesn't involve forcing the scary ideas to go away, it's purely about changing your response to them. Through changing your response, they usually happen much less often, and feel much less threatening.
