Stigma comes from misconceptions and inaccurate stereotypes about what mental illness is. Stigma can also come from fear. Stigma occurs in many places, it can be something that people feel about someone else who is struggling with their mental health, it can be something one feels towards themselves, and it can be baked into the systems and institutions around us.
One way to overcome stigma is to talk about mental health and to ask questions. The better our understanding the easier it is to see that mental health is treatable and that everyone deserves to be listened to and treated with respect.
