Anyone ever feel like you constantly put on an act in front of others?

You have to put on an act at times, to a certain extent. I used to feel guilty about having to do this, pushing myself to be more "real" but I realized that my natural personality can be very cold and unwelcoming. After years of putting on a super happy, lively, and kind exterior, it took a tool on me. Yes, for a while there I did feel like I was putting on an act to everyone who knew me, now, it is something I am working on.
