What are your experiences with Depression?

Depression, or Major Depressive Disorder (MDD), is a common and serious medical illness that negatively affects how a person feels, thinks, and acts. It causes persistent feelings of sadness and a loss of interest in activities once enjoyed, and it can lead to a variety of emotional and physical problems.

Core Symptoms of Depression (DSM-5 Criteria):

To be diagnosed with MDD, five or more of the following symptoms must be present during the same 2-week period, and at least one of the symptoms must be either (1) depressed mood or (2) loss of interest or pleasure:

1. Depressed mood most of the day, nearly every day.
2. Markedly diminished interest or pleasure in all, or almost all, activities.
3. Significant weight loss or gain, or change in appetite.
4. Insomnia or hypersomnia (sleeping too little or too much).
5. Psychomotor agitation or retardation (observable by others).
6. Fatigue or loss of energy.
7. Feelings of worthlessness or excessive guilt.
8. Difficulty concentrating or making decisions.
9. Recurrent thoughts of death, suicidal ideation, or suicide attempt.
