Works for me, I'm good at putting things into boxes. If I catch a bad feeling or some bad stuff coming up early enough, I can consciously put it into a box and save it for later. I do it by visualizing a huge cabinet with thousand of drawers and a hard disk in each of them. I imagine me saving the thing to a disk, then set a password, then lock the drawer and hide the key. I need several security measures to make sure the thing won’t just pop up back to my head. I don’t remember how I learned to do this, I feel like I’ve always known it. Of course there are problems: I tend to forget what is where, so sometimes I end up looking at something I didn’t expect to see; there are many things locked up in the cabinet and I sometimes forget about putting something aside, so it stays locked for a looooong time. And there is a problem related to time: if I miss the moment and start to feel the bad feelings or think about bad stuff, I can’t put it away. I can only do it before I start feeling or thinking.
