Personally I have used a variety of cognitive coping strategies for many years to get me through from day-to-day (most of these self developed or drawn from NLP rather than CBT which I don't relate well to). However I am finding more and more that there are barriers on an embodied and affective level that cognitive approaches alone do not address (in fact they get in the way because I have always used rationalisation as a form of distancing and dissociation from my embodied self). This is why I use the therapies I stated earlier, but in particular only one of those - Embodied Relational Therapy - was specifically developed to work on armouring so I think is of great relevance to CPTSD survivors (being based explicitly in the body psychotherapy/Reichian tradition).
