Sucide Is never an escape! Sucide is Cowards who dont have faith in them. Everyone goes through difficult times, Life never stays Happy for everyone! All you have to do is to fight, Be patient , be consistent, Don't Panic or get depressed! Getting into drug is itself is not way out of depression.. infact it is a Slow way of sucide! In short if there is a Will, there is a way!
Best way to get out of depression is to stay positive, Look for the people Below you (who are suffering more than you) and then be thankful for what you have!
Best example coming into my mind is Jack Ma! Founder of Alibaba.com.. do read his life story! He was one the unluckiest person on earth, but if he had committed sucide then he was never to be one of the world richest persons
