We often think people will only die by suicide after a long history if depression. Some suicides happen very quickly, one study that asked suicide attempt survivors how long was there between you thinking about suicide and carrying it out, 24% said five minutes or less so it is often an impulsive act. We know poor sleep makes people far more vulnerable to making poor decisions.
