...........10. Fear. A lot of the previous reasons can be boiled down to one big reason — Fear.

• Fear of how others will perceive us
• Fear of what others will think of us
• Fear of what will be done with the information we share, or how it might someday be used against us
• Fear of what the therapist will think of us
• Fear of how others will judge us
• Fear of having our feelings or thoughts dismissed, of not being believed
• Fear of being in therapy for the first time and not really knowing what to expect
• Fear of being told we’re “crazy” or worthless, of being unloved and unlovable
• Fear of rejection
• Fear of the unknown
• Fear of change.

These are all legitimate and valid reasons for “lying” to your therapist. Others — such as intentional manipulation in order to obtain a specific diagnosis for disability reasons or prescription medication for pain relief reasons — are not covered here.
The truth is that psychotherapy is complex and challenges both the psychotherapist and the client to work outside their comfort zone. Change and progress takes effort, and that sometimes means not always being entirely truthful with a professional. But it also means challenging ourselves to try, even when it doesn’t feel natural or easy.
