Wanderlust is a British television drama miniseries written by Nick Payne and directed by Luke Snellin and Lucy Tcherniak.
Emily's husband, Josh (who was also a patient in couples therapy), died by suicide during the treatment.
Joy's injuries and her recovery from them exacerbate the marital difficulties she is having with her husband, Alan.
Joy's affair with Marvin ends but she rekindles romance with her (now married) former boyfriend Lawrence.
Episode 5 consists mainly of a long session with Joy's own therapist (Angela), during which Joy comes to realize her self-destructive promiscuity is a sublimation to avoid the real issues in her life: bereavement from her mother's death and guilt over the suicide of her patient, Josh.
