Just remember that a big part of healing with PTSD is retraining the brain on how to "file" memories. And the good part is that once the brain learns where a certain "type" of memory goes, it will continue working and filing all similar memories, in the background and while we sleep.

No, there isn't any cure for PTSD (yet?) but we can all become better at managing it's symptoms, and healing from certain aspects... become less vigilant, less easily triggered etc.
