Anon145062 - I am so sorry about your experience but the fact that you are interested in help is a positive sign.
I also wanted to let you know that about 5% of Americans or close to 11 million people in this country suffer from post traumatic stress disorder and about 14% of veterans suffer as well.
So you are not alone. The post traumatic stress disorder treatment involves a combination of counseling, drug therapy and psychotherapy.
I know that you say that you were not interested in drug therapy but I just wanted to let you know that medications like Zoloft change the levels of neurotransmitters in your brain and alter the levels of serotonin and dopamine which will reduce the occurrences of flashbacks because it blocks the frequencies of those memories reoccurring.
They are also conducting studies on the effectiveness of Prozac, Celexa, and Paxil for long term use.
In order to find a good therapist in your area you should go to the site Goodtherapy.org and it will offer you a series of psychotherapists in your area.
You can search by state or by zip code. It also offers background information on the therapists in your area. I hope that helps.
