Muslims do not feed depressed or attempt suicide because they believe in life after death, which totally depends on having faith and believe in Allah [God], his prophet Muhammad (Peace Be Upon Him) and the good and bad deeds of his own. Suicide is haram (not allowed) by Allah, so if you or any one you know is feeling depressed or thinking about suicide, please take a look on Islamic teachings (Quran, Hadees) and live a happy and satisfied life in this world and hereafter. Thanks
