The purpose of creating a Blue Mental Health Day flyer is to raise awareness and encourage people to prioritize their mental health. The flyer provides information about the event, including the date, time, and location, as well as resources on how to take care of one's mental well-being. Additionally, the flyer aims to reduce the stigma surrounding mental illness and promote open conversations about mental health. The goal is to help individuals feel supported and empowered to seek help when needed.
