CBT for PTSD and Complex PTSD

People react differently to traumatic exposure.  Some people develop mild discomfort which resolves without treatment within a month and others develop severe symptoms such as tension, irritability, inability to relax or sleep well, emotional overwhelming and re-experiencing the traumatic event or aspect of it.  Many people feel grief-stricken, depressed, anxious, guilty and angry after a traumatic experience.

Sonya offers psychological treatment for the symptoms associated with single, multiple and prolonged traumatic experiences tailored to the type of the trauma and the context of the experience.
