i haven't done hypnotherapy, but i have done neurofeedback for my CPTSD and DID. there are many different NFB protocols one can do, and one of my favourite ones is called Alpha-Theta training. this protocol helps the client get into a deep meditative state or a 'pre-sleep' state. while in this state, i was able to focus on my various dissociated parts/alters and process many truama memories and emotions that many of them carried. NFB also helped me to form a more cohesive sense of myself and promoted self love and worth.

similar to you, i struggled to experience a sense of safety in talk therapy with my therapist and the NFB helped to calm my overall anxieties and fears.

are you planning to try the hypnotherapy again since it was a positive experince for you?
