If an Individual Gets the Feeling That a Friend Is

If an individual gets the feeling that a friend is showing signs of being suicidal, they should:

A) have a few laughs with them and try to cheer them up.
B) take it seriously and seek help immediately by calling 911 or contacting a mental health professional.
C) suggest several books about suicide and its effects for them to read.
D) ignore them, because asking them about it could make them more inclined to commit a suicide.
