I had a teacher who lost his wife & son. He phrased suicide as walking out of a movie early when the film is at its lowest point. You never know if it worked out & it is worth sticking around to see where the plot goes because you already invested time into it. Plus you don't get to pick another film if you leave.

Looking at your life as something to kind of amuse you makes the darker points easier at least for me, & I take time to find the brighter points in the mundane.
