Query: I got PTSD from watching this.

Excellent series. All I have to say is this "explicit" gave me PTSD. In some scenes my heart was pounding and body trembling then I found myself right back in the sandbox which was about six years ago.I gave it 4 stars instead of 5 because it was too real. Brought back memories I'd rather not remember. I thought I was over this, thanks HBO.
