Lost my smile

Who's got the answer to this little question, how do I redirect my minds attention. It's taking over my whole day even most of my sleep, I forget it about for a few seconds then it will repeat.
I have dreams which are pretty much swell, but then I wake up mad as hell.
Thoughts about the same shit different  day, working hard hell to make topic go away. It kind of strange cause it's been awhile, for some reason I forgot how to smile.
