Sometimes my mind just self-destructs. I'll just be sitting and a transcript of my mental talk would read "die...die...die...die" for maybe a minute or more. Or I'll think, in response to a situation "what about me?" Followed immediately by "kill myself." Or I'll be thinking of the sense of self as a concept and feel the urge to "break it." "Break... My sense of self?" "Yes."

Let me disclaim that the mental activity I'm referring to doesn't reflect a desire to commit actual suicide, it's more of a desire to eradicate the mind's tendency to assert it's me-ness through mental talk/concepts. 

Does anything like this happen to you?
