When you have a depression you have an overwhealming sense of being sad without necessarily having a reason to be sad. It may feel like something that comes from a kind of emptiness or heavy-mindedness that has been lingering on for some time, and which one can not put a finger on when it began and you start to think that there is no end to it this overwhelming feeling.
Depression is a depressive mood characterized by aversion to activity, which can affect a person’s thoughts, behaviors, feelings, and well-being.
Depressed people may feel sad, anxious, empty, hopeless, worried, helpless, worthless, guilty, angry, hurt or restless. They may lose interest in activities that were once pleasurable, may lose their appetite or overeat, have trouble concentrating, have difficulty remembering details or make decisions, and can contemplate or attempt suicide . Problems include insomnia, excessive sleep, fatigue, loss of energy, change in food, suffering, pain or digestive problems resistant to treatment may also be present.
Depressed mood is not necessarily a psychiatric disorder. It can be a temporary reaction to certain events or the consequence of a given medical condition or even a side effect of medications or medical treatments. Depressed mood is also the main feature or associated with certain psychiatric syndromes such as clinical depression.
