I also checked her past posts........ that's not a troll in my opinion. Agree that her post, especially if it was 'a cry for help', needs to be reopened to be on the safe side.
Common misconceptions about suicide
FALSE: People who talk about suicide won't really do it.
Almost everyone who commits or attempts suicide has given some clue or warning. Do not ignore suicide threats. Statements like "you'll be sorry when I'm dead," "I can't see any way out," — no matter how casually or jokingly said, may indicate serious suicidal feelings.
FALSE: Anyone who tries to kill him/herself must be crazy.
Most suicidal people are not psychotic or insane. They must be upset, grief-stricken, depressed or despairing, but extreme distress and emotional pain are not necessarily signs of mental illness.
FALSE: If a person is determined to kill him/herself, nothing is going to stop them.
Even the most severely depressed person has mixed feelings about death, wavering until the very last moment between wanting to live and wanting to die. Most suicidal people do not want death; they want the pain to stop. The impulse to end it all, however overpowering, does not last forever.
FALSE: People who commit suicide are people who were unwilling to seek help.
Studies of suicide victims have shown that more than half had sought medical help in the six months prior to their deaths.
FALSE: Talking about suicide may give someone the idea.
You don't give a suicidal person morbid ideas by talking about suicide. The opposite is true—bringing up the subject of suicide and discussing it openly is one of the most helpful things you can do.
