I hear you on this , what I found really helpful was taking up meditation and Tai Chi so it was done outside of therapy. Hyper awareness and hyper vigilance make it seem like everything is going at 200 miles an hour like a racing car , so it feels like life or death , but you can't continuously drive a car at that speed because it will break down. So you need to slow down and even go out of your comfort zone , which can be done with Tai Chi / Qui gong exercises or trauma release exercises. Maybe find a guided meditation that you like to help with the mind chatter , but you need to keep at it and also breathing techniques help.
