Herpes with PTSD

I start having flashbacks due to my PTSD, which causes my body to stress, which causes outbreaks. Then because the outbreaks are painful in ways that trigger flashbacks, it causes more flashbacks and stress that brings on MORE sores. Is anyone else dealing with somethig like this? I’m really trying to stay strong and keep calm but it’s so hard! I’ve tried using coping skills, have been journaling, talking about how I’m feeling but I’m still in a state of sadness and stress. How do you deal with stress from herpes or traumatic events?
