Signs that someone is considering suicide may also show up on a computer. For instance, a Web-browser history may show that a person has been researching suicide and ways to kill himself, Dr. Clayton says. "With a teen, especially, parents should be monitoring Facebook or MySpace," she adds. Asking about suicidal impulses does not "put ideas" in a person's head, says Dr. Robbins. If you're concerned about suicide, you need to ask the person about it directly. If the person has access to guns, medications, or other items that could be used for self-harm, get rid of them. Most importantly, you should contact a health professional.
