I hope you are recovering from your surgery.
I can relate to this. We keep things very separate too. Different parts of us have different interactions with different people. It doesn't work when we meet those people in different settings, or worse yet, when people from two different settings who usually deal with different parts of us are in the same place at the same time. Some parts don't want anything to with some people that other parts interact with. It is all very messy when life doesn't line up like it should. People think we are very moody, run "hot and cold" etc. It makes me wonder how many people who are like that are actually dissociative.
