I don’t really have any advice, but what I can say is it’s not really about distracting myself or avoiding thoughts, it’s more like changing how I think about things. For example, when I get some random aches and pains, it worries me a little. But in the past I would fixate on things, try to treat them, see a doctor etc. After a certain amount of grappling with my own mortality, I kind of realized that sometimes my body will just hurt, and there’s nothing I can do about it, and so I have to sort of say, “ok, I have this pain, that’s fine,” and then just move on to whatever else I need to do. Although sometimes it may mean the opposite, accepting that I
can’t just power through. “I’m just not going to be able to do all the things I wish I could do today, I need to rest instead. That’s fine.”
It’s still hard for me. But I think the biggest difference is that I have shifted my focus more towards the things that are here and now, and that I can actually control, and focusing attention on those things naturally means spending less time thinking about things that are far away or beyond my control. (Ie, applying attention elsewhere is not the same as distraction.)
Not super coherent, but I hope some part of that is helpful.
