Sorry, but DP/DR can't be "self-contained" to the point of having no cause and effect relationship. Whether or not you're aware of what's happening, is irrelevant. Learning that is apart of the process. Wake up
I meant its causality is separate from active cognition. It's a passive sensation, such as feeling cold in a low temperature environment. You can't choose not to feel cold when it's cold.
How would your mind un-decide? I don't know sir, tell me the ways of your mind. Stop putting the term "mind" in a box. By BEING your mind, you control it. And it's up to you to de-couple the relationship between anxiety/thought and it being a trigger. And that next argument is clearly ridiculous. Anxiety doesn't GIVE you DP. Awareness leads to thought. See where i'm going here?
You, as an agent, only exercise control to a limited degree. If someone punches you in the face, is it up to you to choose if you feel pain or not? See, that's why you can't choose not to be depersonalized either. It's something that happens outside of your active control. That's why you can't decide that anxiety doesn't cause you DP symptoms. If it does, then it does-just like being exposed to a substance may cause an allergic reaction. It's a biological causal mechanism, something that's outside of your control. You can mitigate or prevent the symptom by not exposing yourself to whatever is causing the symptom (if possible), but you CANNOT sever the cause-effect relationship.

Why can't anxiety give you DP? It sure is able to cause physiological changes such as sweating, increased heart rate, increased (or decreased) awareness, and so on (or rather, these are caused by a surge of adrenaline/cortisol, but that's beside the point since anxiety is earlier in the causal chain). No, I don't see where you're going here. DP/DR is commonly construed as an anxiety symptom in many cases. Also "anxiety leads to thought" seems like an odd statement. Saying anxiety FOLLOWS from thought would make more sense, a specific kind of thought, since anxiety is a result of psychological distress in most cases, perhaps a disorder of the autonomic nervous system being an exception.
And it's up to you to de-couple the relationship between anxiety/thought and it being a trigger.
"It's up to you to decide not to be intoxicated after downing three bottles of booze".
"It's up to you to decide not to have your blood pressure rise in a state of anxiety/fight or flight".
Maybe you can teach me how to micromanage neurons in the brain in such a way as to counteract the autonomic functioning of your body? Clearly you seem to have such an ability based on what you keep saying.
