Those are good ways to let go. But I find some things are more sticky and not so easy to move on from.

A method I have used to help let go of some long-held “baggage” is 6-Direction visualization. Have you ever used it? Take the aspect of that topic that is most attracting your attention right now, and **put it above your head**. This is simple to do with an easy topic (maybe breakfast today), but much harder to do with a hot/charged one. Do your best, even if it's only with the tiniest piece of it. No need to spend too long at it. OK. Now put it below you. To the right. To the left. In front. Behind. Above again. And so on, until it has released a bit and you feel better. This procedure works best when you're not hungry, tired, under the influence, or distracted. Good luck!
