Final answer:
Layla is likely experiencing major depression, a mental health disorder with symptoms including a lack of interest in activities, difficulty sleeping, and feelings of hopelessness, all of which she has been exhibiting.
Step-by-step explanation:
Layla may be experiencing major depression. Major depression is a mental illness characterized by a profoundly depressed mood lasting longer than two weeks, accompanied by symptoms that Layla is exhibiting, such as a lack of interest in activities previously enjoyed (lack of interest in everything), trouble sleeping (insomnia), difficulty concentrating, and feelings of hopelessness about the future. These symptoms match the clinical description of major depression, which can include changes in sleep patterns, weight and appetite, decreased energy, feelings of worthlessness or guilt, and frequent thoughts of death or su_icide.
Antidepressants are one of the treatments for major depression. Unlike schizophrenia, which may require antipsychotic medications, or social phobia and mania, which have different symptom profiles, major depression typically involves persistent and pervasive feelings of sadness and loss of interest that affect functioning significantly.
