You may wish to check out EMDR therapy Eye Movement Desensitization and
Reprocessing therapy. My wife and I both developed Post Traumatic Stress
Disorder (PTSD) some time after our son was suddenly killed 9 years ago.
We each went to a therapist for grief counseling and therapy. Eventually I got
to the point of being able to move on in my life, but my wife got stuck. They
used the EMDR with her, and it made a very big difference. As I understand
it, the desired goal is to stop the constant memory of the traumatic event
from replaying itself over and over in the patient's brain. EMDR did a good
job of this for my wife.
Neither one of us has PTSD any more, but at the same time, you need to keep
thing s in perspective. Losing a child suddenly like this will always affect
your life forever, and it's not like you ever 'get over it.' But you can get
to the point where you can lead a relatively normal life.
