mj778,
PTSD does not go away on it's own. It becomes more complex, causes more social and physical issues as it is "simmering".
I think another therapist or that same one, maybe...someone who KNOWS PTSD and treatment options. It doesn't improve with your run-of-the- mill therapy either. It needs a trained therapist with a background in treating PTSD. Finding the right therapist is a little tiem consuming and must be taken with as much seriousness as buying a house or car...do research, ask questions and check options. A good therapist can make all the difference in helping you heal.
I have spent 28 years trying to fond out what was wrong with , then finding someone to help me, then being able to afford my needed treatment....I have recently found a therapist that has helped me more in two sessions that anyone else has in the entire 28 years. I had a major breakthrough Monday and I returned Tues for more work, I am now happier and hopeful and being heard! believed! and validated!!
Some treatments and books to look into:




Healing the Child Within by Charlse Whitfield
Recovery of Your Inner Child by Lucia Capacchione
A Gift to Myself by Charlse Whitfield
Family Secrets by John Bradshaw
Homecoming by John Bradshaw

These are some of the resources I have and am using for my healing. The main thing I ahve learned, over the years, is NO treatment and only treating one symptom of PTSD have the same result...no healing and continued distress growing in intensity.
I hope something in this helps you. It is a bumpy road but worth the effort.
