I read a beautiful, troubling excerpt from a fiction book about what trauma does to a person. I thought “Only someone who has been traumatized would understand this.”
We call them survivors, but once the [bad guys] get you, the person you were dies, like any traumatized part of you never leaves that room, that car, that moment, and you walk forward a ghost of your former self. You rebuild yourself over the years, but the person you were isn’t the person you become. The great bad thing happens, and you become a ghost in your own life, and then you become flesh and blood and remake your life, but the ghosts of what happened don’t go away completely. They wait for you in low moments and then they wail at you, shaking their chains in your face and trying to strangle you with them. ~Laurell K.Hamilton, Affliction
The trauma after effects, of any degree, can impact you at any time, with any reminder 
of the moment, people, places, smells, times of day. Those “shaking of chains” are those sneaky fears, troubles, anxiety, depression, panic. Those inexplicable moments of irrational thought. Trauma can impact your sleep, your appetite, your belief about yourself, relationships and your life. It can hit you big or small. Do not under estimate the impact of trauma. Like the excerpt stated, you can rebuild your life and yourself, but those ghosts hang about.

Rosa Luxemburg said “Those who do not move, do not notice their chains.”
This, of course, is mostly used in a political sense. It means much to me in a mental health sense, too. Seems every time I try to make a move toward true happiness, those chains start shaking at me. As though they’re saying, “Aha! Gotcha! YOU aren’t ALLOWED.”
Enjoyed your post – so true.
