Suicide shouldn't be an option. Yes people are going through a lot of difficult situations which result to considering suicide if not properly managed. Imagine someone that commits suicide because he/she couldn't provide for the family, we he now provide for the family from the grave? No. Rather the suicide will bring more pains and agony to the family.
Commiting suicide because you didn't achieve your goal is also wrong because your goal is not in the grave. One way to overcome this incidence of suicide is to find your way around your loved ones, avoid staying alone, and most importantly try to talk to someone about your predicament.
