EMDR is a s a psychotherapy treatment that is designed to alleviate the distress associated with traumatic memories as well as effect change with unhelpful core beliefs. 

It uses bilateral stimulation which can take many forms, including tactile, audio, and visual. 

Attachment EMDR is what I use in my practice to manage overwhelm meaning that we avoid you being in a state of distress. Healing does not happen in state of emotional or physical overwhelm.  We work together to make sure session are within your personal distress tolerance to you.  

It can be combined with Internal Family Systems or used alone.
