Depression is a common mental health condition characterized by a persistent feeling of sadness, loss of interest, and changes in behavior and thinking. It can significantly interfere with daily life and well-being. Symptoms of depression can vary from mild to severe and can appear differently in each person.
These symptoms can include:

• Feeling sad, irritable, empty and/or hopeless.
• Losing interest or pleasure in activities you once enjoyed.
• A significant change in appetite (eating much less or more than usual) and/or weight (notable loss or gain unrelated to dieting).
• Sleeping too little or too much.
• Decreased energy or increased tiredness or fatigue
• Increase in purposeless physical activity (e.g., inability to sit still, pacing, handwringing) or slowed movements or speech that are severe enough to be observable by others.
• Feeling worthless or excessively guilty.
• Difficulty thinking or concentrating, forgetfulness, and/or difficulty making minor decisions.
• Thoughts of death, suicidal ideation, or suicide attempts.
