I get hundreds of messages and comments from children, teens and young adults monthly about how parents respond to “mom/dad, I have been having thoughts of suicide.” I then advise these kids to tell a teacher or a school counselor when a parent isn’t responding.
So if you hear that confession, respond with, “I am so sorry. Tell me more. I am here to help in any way I can.” Then do more listening and no lecturing. Many parents respond appropriately but some do not.
