Introduction: Stigmatization is a very common phenomenon that follows people with mental health disorders throughout history. It is a sociological concept that denotes a deflected attitude and disapproval of society to anyone different. Because of the negative image of people with mental disorders, stigmatization is still very widespread. Purpose: The purpose of the diploma is to determine how stigmatization affects individuals with mental health disorders, and how they respond to it. Besides, we want to find out how self-stigmatization relates to stigmatization. We are also interested in the most common prejudice that society attaches to people with mental health disorders. Methods: In the diploma, we used a qualitative method of research. By prior arrangement, we conducted five interviews with people with confirmed mental health disorders aged between 20 and 35 years. Questionnaires were made using the DISC 12 questonnaire. Results: Young adults with mental disorders are accompanied by stigmatization. As a result of stigmatization, they can self-stigmatize. A frequent response to stigmatization is the negative feelings, such as anger, fear, shame, burden, causing people to hide the illness and not talking about it with people who are not close to them. Friends and family members play an important role in overcoming and tackling the stigma, as they can be trusted. Nonetheless, there can also be people who are indifferent and disagree with prejudice about mental illness. Discussion and conclusion: Many people still do not look at mental illness as real diseases, which leads to misunderstanding and the elimination of people who are considered to be different. People are afraid that this can happen to them, this is why they push away and stigmatize everything different. There is still too little talk about the stigmatization of people with mental disorders. Solution is to educate society about mental illness, which would help them understand the illness itself, and accept the difference and suppress prejudice.
