Existential suicide is a serious and often misunderstood term that refers to a philosophical state of mind. This state of mind can be characterized by feelings of deep despair, meaninglessness and hopelessness. There are a number of expressions that are used to describe this condition such as philosophical suicide, suicidal nihilism, nihilistic despair, and absurdism. These terms all describe the state of feeling like life has no inherent purpose or meaning. It is important to recognize the warning signs of existential suicide such as self-harm, depression, and isolation. Seeking help from a qualified mental health professional can be crucial in overcoming these feelings and finding a sense of purpose and meaning in life.
