I just lay awake with a sense of dread 24/7. I want to ignore it, but I can't.
Push it out of your mind. When it creeps back in, push it out again. When it gets to the point that it seems it will never go away, push it out again, and again, and again. This works for me, and I have actually gotten better with it with time. Eventually, it goes away. There is nothing helpful in dwelling in that place.
And the kicker is that things could be worse. The corollary of that is that things are never as bad as they seem. Sometimes it seems like they are. But you can't solve these problems. You can only ignore them.
I've often wondered if this isn't training ourselves to repress feelings and memories, which is seldom looked as healthy in the world of psychology. I've decided I don't care. Not one person among us is without psychological defense mechanisms. As stupid and shallow as they are, those mechanisms exist as an alternative to insanity. Choose repression in an emergency. It's really no different than obsession or rationalization, or all the rest of the stuff we fool our minds with.
Or as the song says, "Don't worry. Be happy." That little song was much more than just a playful tune. My God! It's more like a personal message from the Dalai Lama.
