About Relationsick
The body wants to heal itself. By treating your relational trauma, you can create the conditions it needs to begin.
Most people know that controlling relationships can lead to mental health issues. But fewer people understand that our bodies translate relational trauma into physical, chronic, and even terminal illnesses— autoimmune disorders, cancer, chronic pain, and more. For people in unbalanced, abusive, or toxic relationships, this means their relational trauma, narcissistic abuse, and oppression is literally making them physically and emotionally sick– in other words, relationsick.
Building on the Internal Family Systems and Relational Life Therapy models, Relationsick is a trauma-informed recovery plan that will help you rebalance relationships where you give too much and receive too little or where someone is abusing their power- at your body’s expense.
Relationsick will help you break free from the fawning behaviors that keep you stuck in toxic relational dynamics- with romantic partners, family, friends, professional relationships, gurus, or other authority figures- so you can heal your dysregulated nervous system, emotions, and body. Drawing on more than 30 years of experience, Drs. Lissa Rankin and Jeffrey Rediger place recovery firmly in your hands through grounded, ethical, trauma-informed, evidence-based medical advice.

– Unpack how religious, New Age, or cultural belief systems can reinforce abuse through ‘spiritual bypassing’
– Deconstruct harmful beliefs that enable perpetrators, cause ongoing harm to victims, and prevent accountability harm you, sotprogram unhealthy conditioning and set patterns that will help your nervous system begin the process of deeper healing
– Get to know the parts of you that cause you to give too much and keep you stuck in power imbalances that can make you sick
– Heal traumatized parts so you are empowered to take a firm stand for yourself and your health
