Who We Are

About Darlene Karst

Darlene has been a therapist since 2006. She has had extensive training in Rapid Resolution Therapy and brain science. Born and raised in South Africa, she has lived on three continents and in three countries giving her a unique perspective and insight into people of all walks of life. 

She has also taught psychology since 2007 and brings her academic background into her office.

Treatment approach

Darlene uses a combination of Rapid Resolution Therapy (RRT), somatic awareness, attachment focused therapy and applied brain science in her practice. 

RRT is a unique therapeutic modality that focuses on the subconscious mind, the seat of most problematic behaviours and thoughts. This therapy approach is very effective with anxiety disorders, trauma and addictions. Since it uses the language of the subconscious results are experienced after only a few sessions. 

Bringing in elements of attachment and somatic therapy allows the therapist to ensure that the root of behaviours are shifted towards what is good for the client. A solid foundation of brain science backs up the activities in the office. 

Client profile

Darlene specialises in working with trauma and PTSD as well as anxiety disorders. Whether you have experienced a single traumatic event or a lifetime of events, this therapeutic approach can make a difference. 

The therapist also applies brain science to couples. Learn to interact in a completely different way and experience shifts towards the kind of relationship you want. 

Another area of specialty is that of any issue related to sex. This office is accepting and empathetic to all questions related to sexual matters.

Why tears are healing

There is a big difference between depression and grief although often diagnosed as being the same. Both of these experiences can feel similar in the body - heaviness, sadness, lethargic, unable to eat or sleep disturbances. However, unlike depression that can be debilitating and paralysing, grief is profoundly healing. 

Perhaps it is our Western culture that has taught us to avoid grief because in South Africa, where I'm from, the traditional African cultures go towards grief openly. There is often a week long celebration of someone's life during which there is wailing and crying. Here, I often get the question, "How will crying and grieving help me?"


Neurochemistry of tears

Lauren Bylsma, Assistant Professor of Psychiatry at the University of Pittsburgh, has a theory that our body releases hormones and toxins through our tears when we cry when we are very emotionally upset. This serves to eliminate some problematic substances from our body which, if they are not released can make us very sick. Tears that are held in can lead to anxiety, physical illness and even depression.  

Tears connect us with our bodies

The left side of our brain is where we store long term memories and it is also the part of our brain that tends to predict the future based on the past and focuses on safety. It is responsible for activating negative affect and suppresses positive affect. It moves forward based on what is already known. 

The right side is responsible for  activating positive feelings and provides new ideas and context, allowing us to have a fresh new perspective.

When we are able to cry and be present with our tears we can effectively activate being in the moment and thus getting out of the left side predictor of the future.
