hmmm one does not have to talk about the trauma to work though PTSD symptoms. Learning ...ah hem relearning how to process events...day to day upsets and triggers helps teach the brain what to do with them, and when you cover something that is misfiled similarly to the trauma, the brain goes AH HA! and processes some of the trauma event.
PTSD isn't cured. If it were as simple as discussing the traumatic event, then we would all "bite the bullet" and be healed! It doesn't work that way.
I'm sorry you have felt this, and suffered because of the belief. Think about all the changes that happened "to" you and the way you live... each area can be addressed...a main area is trust... relearning ways to trust safely. Think about how you breathe now, when triggered... and how that needs to be addressed. Think about the triggers.... without discussing the trauma, you can work through realizing when you are triggered, and how to ground yourself and eventually eliminate the trigger.
There's so much more to therapy and PTSD. I hope you will ask your T and find out just how secure she is in helping you
