The problem I'm seeing is a lot of you also have emotional abuse issues telling you that you're awful people. Don't listen to it. You're wonderful.
PTSD is a complex diagnosis, that, because of some of the side-eye it gets, practitioners are very cautious about using for a diagnosis. If you have been diagnosed, trust in your professional.
Honestly, the entirety of PTSD is so complicated, that anyone who could reliably "fake" it for longer than a hour or two, without a director, an acting coach and someone for consults, should be on Broadway.
