Hi Purple!
Compartmentalising is all the above it just depends on how you work through this information.
I've recently realized after reading "the road less travelled" by M.Scott Peck that DID has been my quick fix solution for nearly every situation I've been in by not experiencing the pain of the emotions I have not truly evolved or grown as a human being by learning from the experiences that occurred. What worked for me in my childhood when trauma occurred has not translated well in my adult life when trauma happens.
Compartmentalising for me is not actually helpful because I am not learning from those experiences and becoming wiser
So I' m trying to review my road map to deal with issues occurring in my life and taking responsibility for what I can own.
