APER - Acute Prorogued Exposure and Reprocessing
The year is 3541 and humanity has found its way into a surprisingly stable culture and world peace - especially with the introduction of alien races and the Unified Republic that spans at least half of the galaxy. Human culture is wholly unique in the sense that it's embraced a cleaner though punkish look, which some historians would likely relate to "cyberpunk". If for nothing else, this often sets humans apart from many of the other races that sport softer buildings and less busy clothing styles often leading them to nickname humans as "busy" or less politely as "a swarm". Regardless of this, humans get along with other species fairly well in a chameleon-like fashion, being the social creatures they've always been. Generally speaking, all of this was possible due the awareness of mental health that especially wiped across the world in 2083.
Therapy is now considered to be as normal as a check-up, the human race as a whole agreeing that mental health being just as important as exercising. Though it hasn't and will never rule out the horrors that some people have gone through, after all mental checks are as voluntary as are physical ones, excluding the processing of particular jobs and their own requirements for employment. There has been a movement to attempt to legally force these mental checks, but a lot of people are on the fence about it, claiming freedom to go in when you need it suits a better environment to face issues.
A new technology has been developed recently called APER or Acute Prorogued Exposure and Reprocessing for those that have trouble or resisting other types of therapy - it is an intensive VR module that stimulates the mind into creating its environment and the traumas related there of. With the help of "divers", these individuals can have help facing these traumas in a direct and empowering way. The success rate so far as proven to be near 90% effective when other methods were close to 3% effective.
Wherever you come from, whatever your race is, whatever your experiences are - you're a rookie "diver". You've been through a few scenarios before and they are roughly the same. The mind of the patient paints a clear picture of the immediate surroundings until the area (room, mall, street, etc) becomes blurry. Depending on the patient, the trauma can be instantly visible while others take some detective work to understand the underlying issue that is present. So far you've been successful and with rather high praise, so your supervisor has recommended you for a special patient suffering from CPTSD (Complex Post Traumatic Disorder) who seems highly resistant to normal methods. The staff already has taking a liking to her for her sweetness and kind nature and somewhere along the line, someone has really pushed for her treatment. This is where you come in.
