I think I do understand what you're trying to get at. That it's probably pointless to worry about certain bad things that could happen because, chances are, it won't be one of those things. And even if you *did* pick the "right" thing to worry about, then you probably couldn't do much about it anyway. And you wasted the time and energy worrying, when you could have spent that time, say, appreciating what you had with the person. Or doing pretty much any other thing besides worrying.

I think some of this for me is my OCD. Where if I worry about a specific thing--and state that worry someplace, or maybe just to myself--it feels almost protective against that thing. (Whereas if I say, "Oh, I'm sure everything will be fine," then it's like I'm jinxing things.) Magical thinking, basically. But I also can't worry about every single thing that could happen to someone, because the list is infinitesimal.

I think it would help me if I could sort of come to accept that I can't control everything that happens. That bad things are going to happen to people I love and care about and to me. That all I know for sure about is this moment I have right now. And to find some sort of peace in that, or at least a level of acceptance.
