Melancholic depression

Melancholic depression is feeling very sad or down all the time. People who have it feel like they can't be happy and they're in a dark and low mood. They might feel hopeless and like nothing can make them feel better. It can last for a long time and can make it hard to do everyday things. Treatment for this kind of depression includes talking to a therapist or doctor and sometimes taking medicine.
