I have been working with a particular middle-aged woman for some time now. We'll call her Brenda. She has been suffering from poor digestive health, multiple sclerosis, and unrelenting back pain for more than 7 years now. Always on edge, she feels categorically unable to relax her body, especially her back.
Upon my asking, she felt the last time she was able to feel fully relaxed was when she was just 8 years old, playing with her stuffed animals in her room. She had some trauma with her parents around that age that persisted for years afterwards and she hasn't been able to feel relaxed since. Imagine living 45 years and never feeling relaxed in your own body.
