I believe that as humans we have the natural instinct to survive. That's why it's so hard to just ctb. We keep hoping that things will get better - thinking maybe tomorrow it won't hurt as much. But the truth is that life doesn't get better. We might have a few "good" moments, but the overall aspect of life sucks. It's wrought with pain (both physical and emotional), disappointment, sadness and loneliness just to state a few.
