Should I tell my therapist everything?

Honesty in Psychotherapy generally leads to better outcomes because your therapist can only help with what they know about. However, you don't have to share everything in the first session - Psychotherapy is about building trust over time. Share what feels comfortable and relevant to your goals. Your therapist is bound by confidentiality, life meaning they can't share what you tell them with others except in specific circumstances: if you're planning to harm yourself or someone else, if there's child or elder abuse, or if ordered by a court. These exceptions exist for safety reasons. Most therapists will explain confidentiality limits in your first session so you know what to expect.
