Hi kora , 
I believe I experienced many brainstem constellations in my life here’s one of them:

I was stuck with a group of friends that hurt me a lot , I wanted to leave them and cut all kind of contact with them but I was stuck for years with them because there are some good friends among them ! 

I couldn’t digest lot of their actions ( assimilation) but at the same time I couldn’t leave that group because I don’t want the good one to be hurt , I guess I couldn’t at that time get rid of them ( no out)! But here I wonder why didn’t the dorsal vagal response symptoms appear ? As I was in a sympathetic response rather than a dorsal one as I was trying to keep on going but I ended up with dorsal vagal symptoms when I decided to leave the group and cut all kind of communication with the good as well as the bad ones ! 
Then I felt depressed for a while ,low blood pressure almost all the time , no energy to do anything ( these were my dorsal vagal symptoms) as I guess I was having this brain stem constellation for a very long time ( long stress phase )moved from sympathetic to dorsal vagal that took months if not more ( prolonged stress phase) 
I know this can also be a new brain theme but it definitely had an brain stem theme constellation that also came up with lots of constipation ( holding on these relationships) as well as diarrhea attacks( not digesting the whole situation) doctors suspected lots of digestive problems , excluding colon cancer after lab a CT scan tests, then doctors suspected this may be Irritable bowel syndrome or Other malabsorption disease that they didn’t confirm as i refused to do further tests 

I don’t think this constellation came with dorsal freeze response , I think I was fluctuating between constipation an diarrhea , sometimes it was severe constipation attack , and sometimes it will become severe diarrhea attack but both comes with very low blood pressure feeling no energy , dizziness, fainting sometimes I was always ending in Emergency room hospitalized because of these severe attacks . 
I guess they were healing peaks of a brain stem constellation conflict 
I felt also isolated when I decided to leave that group as I felt no one understood my feelings , that when KCT syndrome aggrevated some symptoms and appeared at that time with moe belly fat and swollen feet (water retention) , puffy eyes in the morning but also with the attacks I lost lost lots of weight and I had sleepless nights ( stress phase) then after months I gained lots of weight and I was sleeping more but my sleep was of a bad quality sleep as doctors said , I think this was a dorsal vagal sleeping pattern , Plz clarify this from your point of view Kora as there were lots of overlapping stress triggers at that time as lots of mind thoughts and fears that I guess make it hard for me to distinguish things properly.
What’s remarkable that sometimes I had some heavy sweating at night ! Does that mean healing from KCT syndrome conflicts?
