Most people who develop thoughts about suicide have already been diagnosed with depression, bipolar disorder, or some other psychiatric disorder. As a result, they may continue to have symptoms, even when they are receiving treatment.
Many people who attempt suicide talk about it before making the attempt. Sometimes, simply talking to a sympathetic, nonjudgmental listener is enough to prevent the person from attempting suicide. For this reason suicide prevention centers have telephone "hotline" services. Again, do not ignore a suicide threat or attempted suicide.
As with any other type of emergency, it is best to immediately call 000. Do not leave the person alone even after phone contact with an appropriate professional has been made.
If you need immediate assistance yourself, call Lifeline on 13 11 14.
