I wasn't in the armed forces, or have combat PTSD. I did have sexual assault related PTSD and found a therapy that can be used to treat ANY kind of PTSD... is in fact frequently used with combat PTSD. It saved my life. It sounded like hocus pocus at the time.. I held NO hope of its actually working but I was already in the office, already paying for the hour visit so I gave it a shot. Two sessions later I could actually control when I thought about what had happened to me... It doesn't erase the memories but they won't accost you in the middle of the day, in the middle of work, you won't suddenly feel them in your hands, hear their voices... It only comes up when you try to tell someone about it or try and think about it (which of course isn't often! Who wants to relive those moments for no reason?)
The therapy is called EMDR therapy... Eye movement desensitization and reprocessing. There are a couple of ways it can be done... some do it by having your eyes follow a laser on a screen as you visualize what happened to you... but you have to keep your eyes open for that and I found it hard to visualize with my eyes open. The other way is to sit with your hands on your knees, palms down, and visualize, while the therapist taps the back of your hands... one then the other. They'll stop every few minutes, check on you largely because you stop breathing, you get so deeply into it. It took me two sessions and I went from a total mess to having total control. I never thought it would work but it did. I know it sounds nuts but give it a chance. Find someone who specializes in this. It's worth it!
