Most people who are depressed or who are thinking about suicide don't or won't talk about how they are feeling. They feel worthless. They have no hope. They deny their emotions or think that talking about their emotions will be a "burden" on others because no one cares. Or they are afraid others will make fun of them.
That's understandable, because when someone mentions suicide, others may treat it as a joke or deny it. Those reactions only make the problem worse. So, if a friend or relative brings up the subject, take it seriously and take some time to talk about it.
