Most of my thought loops only show the good times in my past relationship, sort of like black and white thinking, so I've been introducing the negative aspects/memories once the thought loop has taken over, trying to see the past (and present) more objectively. But hopefully with this new knowledge I can starve them once and for all.
Notice that in the posts you quoted, the useful response was to one way or another
consciously direct though / attention to other things, rather than allow it to mechanically continue down the same line. We have to choose to act consciously if we want not to suffer endless negative thought loops.
It’s really hard to grasp that these things can be purely mechanical, they just ‘happen’. Just as when driving a car it just ‘happens’ with very conscious input, centers can do things pretty much on their own, can think, speak, write. It thinks, it speaks, it writes, it daydreams.
Scary really, and that’s not to say I don’t ever struggle with same. We just have to learn and remember exactly what is happening in us so that the next time we can more quickly choose a way out of it, rather than loose too much time and energy indulging it. Sometimes I talk myself down as it were, if it’s a narrative, if it’s a musical loop you can change the tune, switch it to a instrumental piece perhaps. Or as Redfox suggested, try focusing on breathing for a while, but add the Prayer of the Soul to it as a way to consciously counteract the negative loop.
You can’t ‘think’ two things simultaneously, choose consciously to give the mechanical mind something else to do will help, choose something useful to your aim then all the better!
