How Do You Do It?

To give light to those who sit in darkness and in the shadow of death, to guide our feet into the way of peace.
Luke 1:79

How do you do it? Tell me how? How do you keep yourself from going over the edge? I know they say it’s all in the head. But for the love of self, how do you do it? My heart beats like a hummingbird wings, chills run down my spine just trying to hold onto the last straw.  O please, help me cause I don’t know how long I can keep this up.  Leave me alone.  Please, stop tormenting me.  Why? O why!
