People who claim they are going to kill themselves all over the internet will not likely commit suicide.
They usually say so only to get some attention.
Real suicides are never really spoken of before the act. Sometimes just slightly hinted (which makes them even harder for the people around to cope with). People claiming openly that they are going to kill themselves have nothing in common with them.
Usually when said people actually kill themselves, it's often just a false attempt gone wrong. You can tell by the mean employed for the suicide.
