I've read about existential anxiety recently, and it resonated with me greatly. It's a feeling of dread with which you encounter things that you could have done that terrify you. I remember panicking as a child, standing on the balcony and looking over the edge of the window, three stories down; and being terrified that I might fall down, despite the balcony frame staying aguard to my equilibrium. Human beings are like that. We're terrified of becoming something - of the possibility of being something - that we can't even fathom, that we can't relate to. So, how do we get over it?People want to believe they are good and compassionate people so they dehumanize the addict. Just like how we dehumanize Hitler to avoid accepting that humans are capable of evil.
