I am both introvert and extrovert. I talk to those I trust about things but not to those I don't trust. I used to be so introverted I didn't want to talk to anyone about anything. Going to group meetings changed me to talk more about personal things. But outside of a group I don't talk about much personal. But I have not gone to group meetings much in the past years so I am more introverted again. Give me some alcohol, though, and I may talk more. I'm trying not to rely on alcohol though and really think being introverted is quite okay. You never know anymore who you can trust.
