Hi Juniper. Although I remember having one flashback 20 years ago, my ptsd seemed to come out of the blue while being counseled for anxiety and depression from job loss, last year, just like you. The whole experience has been painful and emotionally draining. My anxiety seems to have become even worse than before since the ptsd started. If your ptsd is from child abuse and/or neglect it is called complex ptsd. It is the most serious form of ptsd and not really the easiest to treat either. My care givers told me it's more about managing it than curing it. There's no cure or magic pill for it.
I'm taking Seroquel 75 mg @ night to calm my emotions and help me sleep. It gives me a real nice sleep with no grogginess in the morning. Maybe you can ask to go on that.
