Being an alcoholic can change a person’s personality over time. Chronic alcohol abuse can lead to changes in the brain, which can affect behavior, mood, and thought processes. Alcoholism can also cause social, occupational, and legal problems, which can contribute to feelings of anxiety, depression, and low self-esteem. Over time, these changes can lead to changes in a person’s personality and behavior, such as impulsivity, irritability, and emotional instability. It is important to seek help if you or a loved one is struggling with alcoholism to prevent further harm to one’s mental and physical health.
