types of mental disorders

Mental disorders are health conditions that affect how a person thinks, feels, and acts. Mental health statistics show that 43.8 million adults in the United States experience mental illness in a given year. Although mental health problems are very much common, there’s still social stigma and discrimination attached to them.

People with mental health disorders say that they are hesitant to reveal they are mentally ill because of the potent attitudinal barriers they encounter daily. It’s everyone’s responsibility to educate individuals about and raise their awareness of mental health problems.
