Unfortunate, the whole landscape on this is littered with mines and finding truly knowledgeable help is difficult, most seem to just push their favourite flavour, regardless of the patient.
Any successful form of trauma treatment will first make it worse, because you open the can of worms and begin to go deep. Unfortunately, many therapists are not very good at explaining that up front. If you only have a few sessions, it is basically guaranteed to make matters worse. That's a sign that it is working (but maybe a sign to switch therapist if it wasn't explained well and cautioned about; making sure the environment and person is ready for it should happen first...).
