Support for Survivors of Narcissistic Abuse

Narcissistic abuse can leave deep psychological wounds — confusion, self-doubt, anxiety, reputational harm, and emotional exhaustion. Survivors often describe feeling gaslit, publicly shamed, or chronically undermined, sometimes for years.

Tammy provides informed, trauma-aware support for individuals recovering from narcissistic abuse. She understands the complex dynamics involved — including manipulation, smear campaigns, blame-shifting, and coercive control — and helps clients regain clarity, stability, and confidence.

Therapy focuses on:
• Rebuilding self-trust and identity
• Strengthening boundaries
• Reducing trauma symptoms and hypervigilance
• Developing strategies for managing ongoing contact (where relevant)
• Restoring emotional safety and personal power

Healing is not about proving your experience to others.
It’s about reclaiming your sense of self.

If you are recovering from narcissistic abuse, you don’t have to navigate it alone. Support is available.
