Persona
As a high masking autistic woman this hit me hard. I too seal my true self away in the depths of my mind making it mute and motionless as I wear the mask that people wish to see because whenever I'm myself I happen to be rude, cold, selfish and rotten. It's pretending to be as you lose your sense of self and replace it with a bloodsucking void until there's nothing but emptiness within the shell of a childish pleasant persona. You die but you still have to pretend to be alive.
