An artificial reality system and method dynamically provides digital content to a user for treatment of a mental health condition. A digital content processor transmits digital content (e.g., a video stream) to a user. A state detection system monitors one or more states of the user as the user interacts with the digital content in a virtual environment. The digital content processor receives information from the state detection system and/or input from a clinician device about one or more states of the user, and generates a modified video stream based on the information and/or the inputs. The digital content processor transmits the modified video stream to a device associated with a virtual reality platform.
