Therapy for DID and OSDD: You Deserve a Therapist Who Gets It

Finding a therapist who actually understands dissociative disorders — not just in theory, but in practice — is one of the most difficult parts of getting care. Too many people with DID or OSDD have sat across from clinicians who expressed disbelief, minimized their experience, or tried to apply standard trauma protocols without the specialized knowledge these conditions require.

This is a different kind of practice. Liz Calabrese has advanced training in dissociation-informed care, structural dissociation theory, and ego state therapy specifically because she believes that people with DID and OSDD deserve treatment that genuinely fits what they're living with.

Understanding Dissociation

Dissociation is not a disorder in itself — it's a survival response. When the mind encounters experiences that are too overwhelming to integrate, it does what it was built to do: it compartmentalizes. Feelings get split off. Memories get stored in ways that don't connect to the rest of what you know. Parts of the self develop distinct roles, perspectives, and sometimes separate senses of identity.

This is not weakness. This is the nervous system functioning as it should under impossible circumstances. The goal of therapy is not to undo that adaptation but to help the whole system — all parts — live more safely and coherently in the present.

DID vs. OSDD: What's the Difference?

Dissociative Identity Disorder (DID) involves the presence of two or more distinct personality states or identities, along with significant amnesia between states. OSDD (Other Specified Dissociative Disorder) is a closely related condition that shares many features of DID but does not meet all diagnostic criteria — for example, the amnesic barriers between parts may be less complete, or the distinctions between parts may feel less discrete.

Both DID and OSDD exist on the same continuum of dissociative experience. Both are rooted in early, chronic trauma. And both respond to the same foundational treatment approach: building internal communication, safety, and cooperation among parts.

The Treatment Approach: Phase-Oriented, Parts-Based Care

Effective treatment for DID and OSDD follows a phase-oriented model grounded in international clinical guidelines. This is not a process of rushing to trauma processing — it's a process of building the internal conditions that make safe trauma processing possible.

• Phase 1 — Stabilization: Establishing safety, building coping resources, developing communication and cooperation between parts, reducing crisis-level symptoms. This phase often takes longer than clients expect, and that's appropriate.
• Phase 2 — Trauma Processing: When the system is stable enough, gradually working through traumatic memories using EMDR and ego state therapy — at a pace that the whole system can tolerate. No part is forced. No timeline is imposed.
• Phase 3 — Integration: Building a coherent, connected life — not necessarily fusion of parts, but a collaborative, functional internal relationship that allows for full presence and genuine choice in how you live.

What Working With Liz Looks Like

Sessions are online, private, and structured around your system's pace. Liz will work to get to know the parts of you that are present — with curiosity and without agenda. She will not pathologize your experience, push for faster progress than feels safe, or treat any part of you as a problem to be eliminated.

She integrates EMDR, somatic therapy, and ego state therapy within a Polyvagal-informed framework — meaning she pays close attention to the nervous system cues that indicate whether the work is going too fast, too slow, or just right.

Frequently Asked Questions: DID & OSDD Therapy

Q: I've been misdiagnosed before. How do I know if I have DID or OSDD?

Many people with DID or OSDD have received other diagnoses first — PTSD, BPD, bipolar disorder, or treatment-resistant depression — because dissociative disorders are underdiagnosed and often misunderstood. Formal diagnosis requires a thorough clinical evaluation. Liz can conduct a clinical assessment as part of the intake process. Common signs that dissociation may be a significant factor include memory gaps that others tell you about, feeling like different versions of yourself in different contexts, hearing internal voices or conversations, and significant time loss.

Q: Is online therapy safe and effective for DID?

Yes, when conducted by a properly trained clinician who understands the unique needs of dissociative clients. Online therapy offers some real advantages for people with DID or OSDD: you're in your own environment, which can feel safer for difficult processing work; you have more control over your physical space; and you can more easily access your own grounding resources between sessions. Liz has extensive experience conducting dissociation-informed therapy online and adapts all methods appropriately to the teletherapy format.

Q: What if some of my parts don't want to be in therapy?

That's extremely common, and it doesn't mean therapy can't work. Parts that resist therapy are usually protecting the system in some important way — and those protective motivations deserve to be understood and respected, not overridden. Liz's approach specifically addresses parts that are reluctant, avoidant, or hostile toward the process. Building trust with those parts, rather than pushing past them, is often some of the most important work in treatment.

Q: Does Liz work with systems that have child parts?

Yes. Many dissociative systems include parts that carry the experiences and emotional states of different developmental periods, including childhood. Liz is trained to work compassionately and carefully with child parts — honoring their needs and perspective while ensuring that adult functioning and stability remain the anchor throughout the process.
