I feel this, so much. When we feel there is no other outlet for the pain, we go to what is most self-destructive, and there comes a point when we even acknowledge the consequences, but it simply doesn't matter.
Those last lines hit the gut, especially when we are sometimes told how our pain is temporary and will go away. We seek the little relief in order to stay alive, in order to get through each day, even though it gives us scars, sometimes this is all we can do to keep going. To silence the voices and heaviness in our mind.
