Empty
@PoppyRobin Emptiness can definitely be a part of depression. Some people feel numb, empty, and apathetic when they are depressed. Other people experience more saddness, hopelessness, and worthlessness. Many people also lose interest in what they used to enjoy. Everyone experiences mental illnesses differently.
@hopefulPower94 is see. Is that why I lose my appetite when I'm depressed?
@hopefulPower94 This is interesting, thanks for sharing. I always thought depression was mostly sadness rather than feelings of numbness.
As hopefulPower94 said, a feeling of emptiness can be a part of depression. Even more interesting though is the fact that emptiness is sometimes an indication that you're pushing some trauma or emotion away. Emptiness can be an emotional escape as "...feeling nothing is so much easier than being angry or sad all day."
