What is stigma and how does it relate to mental illness?

Stigma is the reaction that the public have when it ties down to those who struggle with mental illnesses. There are two different types of stigma, self-stigma, and public-stigma. Self-stigma is what happens when people with mental illnesses turn against themselves, while public-stigma, as stated before, is how the population in general views mental illnesses.

I hope this gives you a general idea. Let me know if it doesn't fully answer your question.
