Rape Leads to Insanity

Rape Is a Special Kind of Evil and is a horrible thing to have to experience. In most cases it can negatively affect the mental health and cause depression and sometimes lead to Sanity Slippage. With this trope, a woman or man who is raped experiences significant Sanity Slippage and may or may not regain their sanity. Compare Shell-Shocked Veteran (another common portrayal of PTSD), Break the Cutie, Rape as Drama. Sometimes the rape might not have actually happened and it will just be Attempted Rape.
