The initial change? I don't think you could call what I did coping. Total isolation, living entirely off the grid, seeking out any and all forms of relaxation and meditation I could to keep him at bay. It took a hell of a long time for me to come to terms with being both of us at once.
This? Just not having him around at all? It's empty. Probably because I've gotten so used to him being there, and because I've worked so hard for us to safely share one body.
