I fixed my ADHD with traumahealing, especially developement-trauma and a good raw nutrition with an active detoxification of the body.
In childhood i was always active, could never be still and was unable to concentrate. Now i can concentrate better then ever before and become calmer every day
Simply said, nowhere regarding ADHD.
The first thing is that your REALLY want healing. And you have to be open for everything. Then nothing can stop you. Its simply connection knowledge, trying many things, view and recognicing changes and that for many years.
A good source are the books from traumaheilung.net. They are in english available too.
another source is Stephen Porges- the polyvagaltheory. an easier source is Allien Lapiere- healing developement-trauma.
honest sharing by Gopal Norbert Klein is a very easy selfhelping method.
To be honest i can tell you TONS of knowledge in every detail. How everything works, why it works etc. But thats too much for Reddit.
But i have telegram if you want to know everything
