That thing you think about seems compelling.
The issue, the problem, the thing that's bothering you.
You've been told you need to think about IT.
Can you let whatever-IT-is BE for now? Can you stop - just for awhile - trying to figure-shit-out, how-when-or-where it got started, fix it, change it, or end it?
It seems counter-intuitive to let it go - to *not* think about it. It's there and you don't want it, which you think means you need to eradicate it from your life - obliterate the son-of-a-bitch.
But it's not going away. You can't get rid of it. It hangs on like a monkey on a tree.
Putting more attention on IT doesn't make IT go away any more than staring at something will make it disappear.
It doesn't work that way.
Whatever you focus on, is. What you put your attention on, is. What you think about becomes.
There's no way of getting around that.
So for now, can you think about something else? You don't have to think about that right now...
If you can let it be for awhile, it'll get better.
