Healing Complex PTSD and the Vagus nerve

I happened upon a YT channel on childhood trauma and the woman spoke of (C)PTSD. Complex Post Traumatic Stress Syndrome.
I had never heard of it, but the stuff she explained in her many vids resonated greatly and made me realise that I have CPTSD...

She mentioned the name of another woman who also did courses on it like her, but who had written a book on the subject of Polyvagal Therapy as well.
Polyvagal therapy is a method with which you can heal your CPTSD.
I looked that woman up, found yet another name of another woman who fine-tuned the polyvagal therapy, Deb Dana.
I bought a book by her and another one that I came across on the Nervus Vagus & the Chakras.

What it means when you have C-PTSD is that trauma dysregulated your nervous system and if that doesn't get regulated it can create all kinds of trouble in your life, from issues with socialising, finding love, to chronic ailments that doctors cannot explain nor treat.
Also illnesses btw that can be alleviated/treated in the long run.

So if you've had trauma it wreaks havoc in your life. And hell yes, does it do that!!

I'm currently reading in my 2 books that both have exercises. I also bought a card deck by Deb Dana on polyvagal. Each card has an exercise that make you go deep into yourself, all helping to resolve the trauma.

Polyvagal therapy works with the Nervus Vagus, the longest nerve in our body that has 3 branches. 2 of these have to do with fight, flight, freeze, the other is the more joyful branch.

There is also actual polyvagal therapy with a therapist. I've inquired about a 10 week course that is free as it's covered by healthcare.
I've decided I want it sorted. i want to get regulated.
For now I'm doing what I can by myself with my books. And obtaining insight and information.

I now also get why I smoke(d) and find it so so hard to quit: I smoke to regulate myself.
When I began with exercises from the books I got restless. Clearly things got stirred up, and my urge to smoke reared its ugly head. I couldn't stop it, so I bought some tobacco. It immediately gave me a sense of peace & tranquility.
Not helpful, as it doesn't do your body good to smoke, it actually triggers a stress reaction to smoke in the body!

Nevertheless I'm very hopeful, and joyful about it all!
For the first time in yonks I have good hope that I can be cured from my ailments or at least get some alleviation!

Books I got:
Chakras and the Vagus Nerve by C.J. Llewelyn

Polyvagal Exercises, the nervus vagus as source of safety & trust by Deb Dana
Title may be slightly different as I got this one in Dutch.
It's her book from approx. 2021 with exercises from her other book and new ones added to it.
So if you want info & insight this is not the right book.
