I'm also in this boat. I feel as if I can't be my authentic self with anybody including the people who've known and grown up with or raised me. Though sometimes when a person asked that question of if I'm alright I reply in a somewhat dramatic cynical way Noooo. If i'm lucky they'll ask aw what's wrong and being the un-sharing private person I am, the reply is either outlandishly snarky or inappropriate. Though that depends on the person and what mood I'm in.
