It depends on what it is. I used to be a very open personable person who loves & is comfortable with everyone. Well I was in a 7.5 year bad relationship that took a toll on me & my personality, it ended 1.5 years ago!!!!
I'm now kind of shy & sometimes get a slight anxiety around new people/places. BUT I know I have to do it to oveercome it. I don't let it hold me back but I'm not always comfy with it.
