This is a fab short explanation. It is the understanding I have come to after battling complex trauma myself. Recovery for me has been a long process of discovery. To find a better life you need to first learn to feel your emotions and secondly to retrain them. Learning to feel took me years. Meditating helped tremendously because it gave me the ability to focus. And i could turn that focus towards feeling. I have learned to hold my attention on a feeling. Which allows me to calm myself when I am frightened and gradually over time my fear of daily life - which was mostly invisible to me as a younger man - has diminished.

Two hints to anyone that might need help with this. If you think you cant feel anything, consider this. What is the feeling of not feeling anything?

Last suggestion: find a pillow and hold it to your chest. Hug the crap out of that thing. See if you can feel the comfort. Your job as a traumatised person is to learn to feel that same comfort when you need it, but without the pillow. Sounds weird but this is what un traumatised person learned to do before they could ride a bike and promptly forgot that they ever learned it. You need to learn it in adulthood. And fortunately its not that hard.
