Yes I can relate to this. The goal is to be authentic, to be "yourself" and this is very much easier said than done. Perhaps you grew up in an environment where you had to be careful what you said, what you did, in case you upset someone, or "made" someone angry. Perhaps you have learned that you have to "be careful" around others. This is how it was (and is to a lesser extent) for me, and it is impossible to "be yourself" when you are constantly on your guard, with all the background mental processing and worrying going on.
