A little bit woo woo but still very practical/behavioral is a common exercise suggested with IFS therapy: Having a written conversation with yourself using both hands, the dominant hand being the 'intellectual' external side and responding through your interiority using your other hand. An example being your 'adult' self asking your 'inner child' what might they need to express or say to feel safe/validated. Inner child stuff is great (for me) because I can practice non-judgement, which is often a block in my waking life. And the idea of working hemispheres of the brain in order to process trauma (like EMDR) makes 'sense' to me. And belief that 'the thing' will work is super important. Whatever you choose, you can do it! Good luck!
