[Mindfulness.]

This is a very good question.
For me personally, I don't feel comfortable in talking to people about how I feel besides a mental health professional. Even then, I question as to whether or not they really understand. It's something that I never really have done, even when I was younger, and I've gotten into the habit of just keeping things to myself. I also think that it's no ones business to know what I think or how I feel.
