First, read the English article below.

If you are experiencing the suicidal feelings described above and believe you are imminently at risk of committing suicide (i.e. you have a plan and the means to carry it out), call 911 immediately. You are in need of emergency help. While you are waiting for first-responders to arrive, call the National Suicide Prevention Hotline at 1-800-273-TALK. This will help pass the time and decrease the risk until help comes. If you are having suicidal thoughts and feelings but do not have a plan, make an appointment with a therapist or counselor. If your situation worsens while you await your appointment and you develop a suicide plan, call 911.
