Anxiety is a mental health condition characterized by excessive fear, worry, and nervousness that interfere with daily life. Both conditions require early identification and appropriate psychological intervention. The symptoms of addiction vary depending on the substance or behavior involved.

They may develop tolerance, requiring increasing amounts of the substance to achieve the desired effect. Withdrawal symptoms such as irritability, sweating, trembling, nausea, anxiety, insomnia, or depression appear when the substance is reduced or stopped. Addicted individuals often neglect personal responsibilities, relationships, education, or work. They may spend excessive time obtaining or using the substance, lose interest in hobbies, experience financial problems, and isolate themselves from family and friends.
