I once read that you can't heal from trauma by thoughts alone. You need to feel the feelings that would have been associated with it, and it definitely suggested things like screaming into a pillow and hitting it. Just a random thought when I read that bit.
I'm sorry I don't have much more to add right now... I am running on empty

I hope that yo7 get some good info here and have a fruitful conversation with your therapist.
Trauma is so damaging and it takes a great deal of effort to heal from, it seems.
