Severe mental illnesses are serious conditions that significantly affect a person's thinking, feeling, and behavior. These illnesses can disrupt daily life, making it difficult to work, maintain relationships, or take care of oneself. Common examples include schizophrenia, bipolar disorder, and severe depression. People with these conditions often need professional help and support to manage their symptoms. Treatment for severe mental illnesses typically involves a combination of medication, therapy, and support from family and friends. Early intervention is crucial, as it can lead to better outcomes. Understanding and compassion from society can also help reduce the stigma surrounding these illnesses, encouraging more people to seek help.
