There are two forms of this basic kind of stigma:
A) If you behave or otherwise express any form of psychological, cognitive, or emotional stress that means you’re not functioning at optimum, people and organizations often react by providing LESS accommodation, not more. Your range of options gets reduced, not increased. Instead of protecting you from additional stressors or making any additional allowances, they act to protect themselves, their organization, and the world at large from you. Every subsequent behavior of yours is regarded as suspect, so you then operate with a more narrow range of acceptable behaviors than your coworkers and colleagues and other people in your environment do.
B) Regardless of your actual behavior and regardless of any unpleasantness of any sort going on in your head, the mere fact of your known status, all by itself, causes your behaviors and perceptions and viewpoints to be disparaged as delusional and hence not worthy of serious consideration by others.
