Horrifying pain

I'm trying not to scream, and can't stop the tears.  I'm in a black pit of pain, and it's shaped like a cone, so any progress I make immediately makes me slide to the bottom again.  My hands on the keyboard are excruciating.  I haven't thrown up from the pain today and am trying not to.  I feel like I'm going insane.  I can't keep living like this.  This is no life.  This is not living.  This is barely existing.  To exist is to hurt, to breathe is to hurt 100 times worse.  My hands, my back...my elbows, my knees...my neck, my feet...the list goes on and on until I've named every fucking body part I have.  I'm not sure this even makes any sense.  I'm in a pain induced haze.  I can't think, I can't talk because I'm afraid I'll lose the little bit of self control I have.  I exist, but I do not live.
