I agree with unguy in the fact that experiences and symptoms differ greatly. Having suffered with C PTSD for over 20 years (result of prolonged torture trauma) , I have endeavoured to learn as much as possible to acertain why I feel dead inside, and seem to have little interest in connecting with others. My psychiatrist explained this to me, using the term 'Mental Death'...akin to a conscious jolt or severing of the psyche. There is a lot written about this online. The paper attached to link below I found to be particularly informative.

And to all the broken C PTSD sufferers...there may not be a way back, but there is a way forward, the trick is to never give up seaching for the key.
