J.....from my experience detaching is a process. It takes time. I still constantly question myself and if what I am doing is following DB principals. Am I being too nice, are my motivations pure in being true to who I am as a person or are they driven by my W. Like yourself I adopted the DB principals very early on but internally I struggled every day. It is normal. 7 months later I am still a work in progress but my emotions are even keel. No still get sad from time to time but not nearly on the spectrum I was before.
It will get better.....you really are doing great.
