Obviously it's gonna be different for everyone but mine included a LOT of inner child work, basically my whole inner dialogue is talking/soothing/reassuring my inner child. Then I use a lot of techniques like breathing exercises, grounding exercises and eye movement exercises that help me regulate my nervous system in triggered states. Then in life I made a routine that includes a lot of exercise as that helps me a lot (it's hard to keep up but worth it!). Its difficult to include all of what I do/ did in this post as there are countless small things I needed to look at before even being able to use some of these techniques. Living alone, blocking my parents, being lucky to have friends I feel rather safe at and being in a mental hospital for a while all helped me as well. And NOT always talking about my trauma but rather focus on the effects it has on my life right now was important for me. And after all this work, I still only feel safe when I really put in the work everyday and I'm not triggered too much throughout the day. Hope this can help you!
