Okay, I'm about to pass out let's see if I can get through this comment without saying something stupid.

It is possible to effectively erase memories and also halt intrusive thoughts. Once, several years ago, I read on TV Tropes a comment about how it was impossible to stop thinking about something on purpose, because you needed to think about the thing you were trying not to think about. I then realized that if you had a specific memory you could easily recall, you could recall that memory and have something to think about instead of whatever you wanted to avoid thinking about. I had also recently listened to a lecture series on neuroscience, and was aware that memories were stored by encoding neural pathways that cause run into each other. So, I speculated that memories that caused you distress could be removed from any easily-activated neural pathway with the same method. Essentially, If you started thinking about the anchoring memory whenever you start remembering the thing you want to forget, the neural pathways that led to the bad memory would begin to lead to the anchoring memory. I can't verify the neurological reality of what I do, but the effect is about what my model predicts.

My anchoring memory is the turret opera AKA O Cara Mia. I sing often, have a great produral memory and my episodic memory is dog shite, so it's entirely possible that I'm genetically predisposed towards being able to manipulate my own memories like this. Good l7ck, hope it helps, tell me if it worked.
