Anorexia nervosa, bulimia nervosa, and binge-eating disorder constitute the three major eating disorders. While those diagnosed with bulimia may be under weight, at a healthy weight, or overweight, those with anorexia maintain a weight 15% below the weight deemed healthy for their height. Additionally, someone with bulimia may consume thousands of calories in a binge before they purge due to fear of weight gain or stomach pain while many with anorexia refuse to eat because they view themselves as fat often despite their body's state of starvation. Those with anorexia may or may not purge, however, obsessive exercise is common in both anorexia and bulimia. The binging habits associated with binge-eating disorder are similar to those observed in bulimia but lack the purging behavior. Eating disorders can lead to severe heart, kidney, and intestinal problems, among many other detrimental physical and psychological implications. Treatment often includes general medical care, psychotherapy, and nutritional management and counseling. For more information visit the American Psychiatic Association online here.

Psychosis is a break from reality often accompanied by delusions and hallucinations. Common delusions include a delusion of gradeur and paranoia while examples of common hallucinations include hearing voices (auditory) or seeing things that do not exist. One of the most important aspects of this illness is that the psychosis is entirely real to the person experiencing it. The voice they hear is as real to them as this web page is to you, they can touch, taste, see, and even smell it. Other symptoms include disorganized speech, thinking, and motor behavior, as well as the lack of ability to function normally. Arising from both genetic and environmental influences, untreated schizophrenia and other psychotic disorders need immediate medical attention and often require a combination of antipsychotics, therapy, and vocational rehabilitation.

There are several kinds of anxiety disorders including panic disorder, specific phobias, and generalized anxiety disorder (GAD). While physical symptoms may accompany any of these, panic disorder is often characterized by shortness of breath, nausea, sweating, trembling, and shaking. The physical symptoms of a panic attack are often so severe that the person experiencing them often believes they are experiencing a heart attack. A specific phobia is an excessive fear of a given object, situation, or place. This fear often interferes with daily life. For example someone with agoraphobia is often too afraid of a certain situation to leave their house. Finally, GAD is characterized by excessive worrying. Someone with GAD may feel so helpless to their worries that they become irritable and unable to focus. It is expected that these disorders have both genetic and environmental influences (like most other mental illnesses) and are often treated with psychotherapies such as cognitive-behavioral therapy (CBT), but can also be treated with medication.
