I come from within\',
But will take you so far
I can control you completely,
Absolutely tare you apart
Rip you from friends & family,
Pull you into the dark
Loved But yet felt so alone,
For no specific reason at all
Leaving you hurt at the heart,
Thoughts & soul so empty
Like a lonesome frozen Christmas night,
Dark, no light, or coals for a chimney
What Am I?
