I didn't even know where to start, I was going to write a post about Phil lies and cope and I think the best way to make things brief is to say that Phil is severely mentally ill. He has been lying his entire life and he also pignotizes himself into believing his own lies(like with bugsnax),which has led him to be completely divorced from reality. His mental illness is also shown on the outside,he doens't bathe,doesn't wash his teeth,he is obese,drinks all the time,looks 15 years older than he is and he has crazy eyes (look at the photo of him dressed as colonel sanders to see how crazy he looks).
An entire life of coping and lying to everyone(including himself) destroyed him mentally. At this point he is a severely mentally ill autist living in an alternate reality,absolutely nothing of what he perceives himself as has any correlation to the real world and he LIMBs anyone that doesnt indulge his fantasies(which is also why he never leaves the house or talks to anyone IRL,they would destroy this fantasy perception of self he created), no wonder all of his non ironic fans are literal dents, you have to be one in order to not be a detractor.
