PTSD is to blame for my feelings of worthlessness and hopelessness habitually during my life. Sexual abuse by a neighbor when I was six years old, coupled with the impact of living as a daughter of a narcissistic mother was the catalyst. With trauma, both sexual and emotional, I experienced negativity leading to depression. Seeking out therapy has improved the healing process.
On goodtherapy.org they explain Worthlessness
Worthlessness can be described as a feeling of desperation and hopelessness. Individuals who feel worthless may feel insignificant, useless, or believe they have nothing valuable to offer the world. People diagnosed with depression often report these feelings, and children who were neglected or abused may carry a sense of worthlessness into adulthood.
Worthlessness, a feeling that may cause an individual to feel as if they have no significance or purpose, can have a significant negative effect on emotional health. A recent study conducted by researchers at Seoul National University found that feelings of worthlessness were significantly associated with lifetime suicide attempt in adults who reported major depression and had also experienced trauma. The study concluded that, among symptoms of depression, worthlessness had the strongest association with lifetime suicide attempt.
