With at least eight suicides cases being reported at various Delhi Metro stations in the past five months, doctors have attributed depression as the most common factor that prompts people to commit such acts and appealed to society to offer a helping hand to them. Depression can be fought and individuals need to be brave while the society should contribute to their recovery by not stigmatising the ailment, they said. From young to old, at least eight cases of suicides were reported between April-Oct, with five of them taking place in September alone. Besides, seven other people attempted suicide between April and Oct 9, some of whom were battling depression. Experts said stressful life in metropolitan cities often contributes to depression in a person, which prompts them to contemplate ending their lives over a duration of time.
