Themes of Existential Obsessions:
 

a. Meaning of Life: Individuals with existential obsessions may obsessively question the purpose or meaning of life. They might find themselves preoccupied with existential concepts such as the nature of existence, the universe, and the meaning behind their own existence.
 

b. Identity and Self-Concept: Obsessions may revolve around questions about personal identity, the nature of the self, or doubts about one's authenticity. Individuals may experience a heightened awareness of their own existence and grapple with questions about who they truly are.
 

c. Mortality and Death: Existential obsessions may involve intense fears or preoccupations with mortality, death, and the impermanence of life. Individuals may be tormented by thoughts about the inevitability of death or the unknown aspects of the afterlife.
 

d. Choice and Free Will: Individuals may obsessively question the concepts of free will, choice, and responsibility. Doubts about the authenticity of one's decisions and actions may lead to heightened anxiety.
 

e. Existence and Reality: Individuals may be obsessively ruminative and vigilant relating to concerns as to whether or not they truly exist, are still alive, or question their reality and their perception. 
 

 

Impact on Daily Functioning:
 

a. Profound Anxiety: Existential obsessions can provoke profound anxiety and distress. The contemplation of deep philosophical questions may trigger an overwhelming sense of uncertainty and fear.
 

b. Compulsive Behaviours: Compulsions related to existential obsessions may include mental rituals (e.g., analysing philosophical concepts), seeking reassurance from oneself or others, or engaging in compulsive mental debates or behaviours to try to "prove" or "disprove" existential concepts, or to reassure themselves that their fears (e.g., not existing) are unfounded. 
 

c. Impact on Relationships: The intense preoccupation with existential questions can impact relationships, as individuals may struggle to engage fully in social interactions or may withdraw to cope with their obsessive thoughts.
