well that all depends on exactly what you mean. If you mean that you are having occasional thoughts of suicide you should probably seek professional help and see if there are any underlying issues and possibly address those. If you are thinking of committing suicide at the moment i would say call a hotlineIn the U.S. call 1-800-273-8255
