The correct answer is a stigma.
Step-by-step explanation
A negative attitude or opinion about a group of individuals based on a characteristic they share, such as a psychological disorder is called stigma.
A stigma carries the prejudice and stereotypes that come from misconceptions about mental illnesses. As a result, people who have a psychological disorder suffer discrimination because of their mental condition.
Moreover, they don't have opportunities to have good jobs, appropriate health care and safe housing among other things.
