So, what does PTSD actually feel like?  

Boy, there is not enough time in the day to write all these things down.  But to me it's the overwhelming fear and dread that is like a wet blanket draped over you to the point that you can't even breathe.  It's the butterflies in your stomach that constantly swarm, even when you are sleeping.  On a 0-10 scale, with 10 being a full-blown panic attack (I know because I just had one that hospitalized me) it’s at a constant, never wavering 7.  It's the pounding headaches that rarely subside that sometimes takes your attention away from your stomach.  Lack of focus or brain fog is with you for periods of the day and sometimes all you can do is sit and stare.  At the end of the day you are so exhausted that all you want to do is fall into bed before you even have dinner (that’s if you can eat at all).  More later, I need to go for a walk now.
