I quit therapy because my analyst was trying to help me behind my back.

The line is a self-deprecating joke built on paranoid inversion: therapy is explicitly meant to “help,” yet the speaker treats help as a covert, almost hostile act—“behind my back.” It satirizes the defensive posture of someone who both seeks relief and resists vulnerability, turning the therapeutic relationship into a comic battleground of suspicion and control. The humor also plays on the stereotype of the anxious, neurotic patient (a persona Lewis often embodied) who can intellectualize or mistrust even benevolent interventions. As a one-liner, it compresses a whole character psychology: fear of being known, fear of change, and the impulse to sabotage support.
