When one is about to die, such as through old age, one might experience a type of existential loneliness. Fear of the unknown or death. What would happen after you die? Will people still remember you? What’s on the other side? Will your existence cease from that point onward? What has your life been about? What have you accomplished?
I learned this concept in development psychology (insert developmental phase) where often people who are aging will start looking back in their life near their final years. Summarizing what has been and what they have accomplished. And in my counseling psychology class, I learned of a concept called existential loneliness where one experiences a type of loneliness near death.
