Yes, what stopdog says. I know as a young adult when I was really messed up I would express suicidal thoughts but that was because I did not know how to express my need for help any other way. I did not know how to express myself and my range of emotions yet before I was taught how and practiced in therapy. We have to learn about emotions and their expression growing up, just like everything else, and, unfortunately, I don't think many get good quality lessons in emotional subjects these days.
