This is a very good question. In my view, we’re extremely complex beings. Many evolutionary biologists consider that we developed our enormous brain capacity so that we could better negotiate the intricacies of social life.
I think it’s a mistake to see your “true self” as being your feelings and opinions. Insofar as you have a self, it lies just as much in your social entourage as in your feelings. That’s what being a social animal involves. Your true self is just as much “out there” as “in here”.
All of the little dances we do to maintain our social selves and keep our relationships working smoothly are not necessarily “disguises” just because they may come into conflict with our feelings at a given moment. We just sometimes prioritize the needs of our social self over the urgings of feelings. That’s an important thing to be able to do.
Inattention to feelings is a problem. Inattention to the social self is also a problem. To be true to your “true self” requires attention to both.
