+ Hedonic adaption: Hedonic adaption is special psychological effects that explains about how we perceive about happiness. Even after a big happy moment, our level of happiness do down quickly. We adapt our perception to our current situations. So it's like nothing will last forever. Hedonic adaption is both good and bad. It makes us adapt quickly with any situations. It keeps us safe. So we should appreciate it and learn how to make use of this effect rather than blaming it. Learns to attend with everything you do even it's bad, explore something news. It will help you deal with bad effects of hedonic adaptation.
+ Mindfulness: Do some mindfulness exercise. We feel stress because our mind think we're having problems. Our mind made up our feelings to keep us safe . It's good for us. Mindfulness help us understand more about feeling and more enjoy the moment.
+ Mind body connection: Your health affects your mental, and your mental will affect your health. To me, it's not because some spiritual belief, but it's how systems work  . Our body, our mind are systems. They are part of bigger system. They connect each others and interact with each other, sending some feedback. So try to improve both your health and your mental. Try to improve your health diet, do exercises and taking care of our thoughts and feelings.
+ We aren't rational. Our thinking system is optimal but it has limitations . It has a lot of problems (cognitive biases). Learn to appreciate and find a way to make it better. For example, we can adapt. We update our belief overtime. Try to make new better habits. Make small steps.
+ There isn't perfect things. Every systems aren't perfect. Our immune system, our cognitive system, organizations, data structures, design patterns,... Appreciate what works, what not and improve it.

Well hey there I think you're on to something here!
Trauma can be a sticky thing, especially long term severe abuse in childhood. We all have stress responses that are designed to keep us safe. If a tiger leaps out of the woods on your morning walk to school your body will rocket into a state of fight-or-flight to keep you safe. In a normal situation, when you're able to run from the tiger or the zookeeper catches it your body will realize the situation has been resolved and you are now safe. It sends the "all safe" signal, the stress response smoothes out and your subconscious is able to process the experience and integrate it into the story of your life experience. "Remember that time the tiger escaped from the zoo and we almost got eaten on the way to school? Whew! That was close haha!" Feeling safe in a nest of family and friends is also vitally important. You can share the story, bond over the experience and move forward together.
But what if the traumatic attack was never resolved? What if that tiger held you down over and over again and beat and brutalized you? What if the tiger was your father or your mother, the very people you rely on to take care of you and protect you? Now who do you tell? You're tiny, the tiger is big and strong and it hurts you over and over again every day.
When the body goes into a flight-or-flight response big metabolic changes occur to get you ready to fight for your life. Digestion is stopped. Complex thought and long term planning cease. Blood rushes to your arms and legs to prepare you for battle.
All pain is the same. Whether it's caused by a broken arm or emotional abuse, the neural circuitry in the brain is the exact same. It's said that "neurons that wire together, fire together". Pain responses can be conditioned, learned and seared into your mind and body.
Maybe you outgrew that tiger attack... sort of. But if you weren't able to actively do something about it or process the guilt and shame of that experience you are still carrying around that incomplete memory somewhere in your body. Body memory is different from a cognitive memory. The narrative version of our lives, which we tell to people to describe who we are, is a different version of memory from the physiological memory where trauma is inscribed. Traumatic memories do not come with a start, middle and end. Instead they reappear in fragments, particular smells, the color of the wallpaper, the timbre of someone's voice heard through a thin wall, the sheets of a bed pulled up over your face. These traumatic memories cycle over and over again outside time. It's as if they're happening NOW and on some level they're happening ALL THE TIME. It may be subtle, but the body is constantly sending out signals that "I'm not safe! I'm not safe! I'm not safe!"
You may become agitated, angry and lash out. You might also become lethargic and depressed, withdrawn from anything that might throw you off your delicate balance. It may be hard to focus on long term goals or concentrate deeply on a single topic because so much of your energy is subconsciously preparing for another tiger attack. As said above, digestion and normal body regulation is disrupted. The body is flooded with stress hormones all the time. This may have immediate impacts on your emotional well being. Over time, after days, weeks and years of disrupted behavior, healthy eating patterns may be destroyed, sleep may be shallow or barely existent, your persistent exhaustion and irritability may disrupt your social life.
Eventually these symptoms and disruptions can snowball into huge chronic pain problems with excruciating physical symptoms. Thoughts of frustration and shame and self-loathing only exacerbate the problem. It may be as if your emotional immune system is attacking itself, which only adds more damage. Life can spiral out of control.
There is hope however.
The opportunity to heal is available to everyone if you're willing to face and befriend your pain and come to terms with the shadow experiences that have been ruling your life from the past.
After all, what other options do you have?
What happened, happened. All we can do from here is bring compassion to ourselves and move on to brighter things.
The first step is to establish a feeling of Safety. From the tone of your writing it seems like you've found a point of stability and you're taking Big Action to look into the mechanisms of your syndrome. Very well done, you're off to a great start!
I think I will refer you to some Authors who have laid out some extensive groundwork on the topic. Have a look around and continue to explore body based therapies. It doesn't have to be all clinical. If you're able, go out for a swim or take an easy movement class. Try acupuncture and massage therapies. If you can find a talk therapist with whom you feel very Comfortable and Safe, continue to explore that route as well.

I don't know if it was the book, a placebo effect, or something else, but I got better after reading that.
Edit: I've been wanting to try this project for several years now: https://www.ctrl-labs.com. I think something like this is the solution moving forward vs voice coding.
Read this, it matches with Abraham’s teachings. Pain or allergies are your bodies way of telling you something emotionally isn’t right.
Well, I would recommend reading
The first one is a lot easier read and got me healing almost immediately, even when I was reading the book I noticed I was holding it with my right hand. The second book is incredible for gaining a DEEP understanding of why this occurred to you, what's going on and making tremendous insights. I remember reading this book and it felt like the ground beneath my feet was shifting with insight after insight and I have my book marked up with endless quotes and how they related to experiences I had I would write in the margins.
I understand the skepticism and people will think I'm full of shit and that's fine but this is what helped me saved my life, and I'm going on 6 months of vastly improved health and close to 100% now.
This isn't everything and I plan on doing a Youtube video explaining on my channel but here are the major things.
This isn't everything but hopefully it help gets you started. I hope the amount of time and effort I took to write this indicates my sincerity in wanting to help others like I helped myself, because it's transformed and given me a new lease on life and existence. And best of all getting through the chronic pain also is maintaining and managing your mental health, and figuring out what you truly want to do with your life and what barriers are preventing you from fulfilling it like say chronic pain.
Best of luck
The book The Mind-Body Prescription by Dr. Sarno covers this exact topic, and made a huge impact on my life and the life of a friend of mine. It's a worthwhile read for scientifically-minded skeptics who are feeling frustrated that doctors seem stumped by their chronic pain/illness. I had a worsening pain that jeopardized my ability to work a desk job, and that book resolved it in a matter of weeks.
The Mindbody Prescription  and The Divided Mind  are two of his books.
My interest in this started with the motivation to get some relief for the RSI-like symptoms and it's been part of my recovery for a few weeks together with the improved ergonomics.
