What if a student shares with you their suicide plans? What would be your next step as a guidance counselor?

First of all, I would make sure this situation is dealt with extreme care and seriousness. I would sit down with the child and try to understand what he/she is feeling. I would then call a parent or a guardian and notify them of this immediately. I would alert all the required school authorities and make sure they identify the child and help him/her with anything possible to get through a difficult time.
