today i see so many people sad depressed due to various reasons and due to genuine reason but who does not have problems without problems life would have been so monotonous and boring....
its like the twist in the straight road without the twist its not possible to reach the destination...
after over coming our problems we will never be the same maybe a tinne minne change but we will evolve as a person mentally and spiritually... we will grow become more matured... 
and as said before a drop and drop only make a sea so these little changes make us who we are today...
then why do people think that they can not be happy and just accept their sadness instead of fighting it off and instead of removing it from their life's the let sadness make a permanent home in their hearts...
after an emotion breakdown we do require time to over come it no doubt but how much time??
it is a fact that emotional pain lasts for only 20mins after that anything is due to excessive thinking...
wonderful it is that our thinking itself is the reason for our downfall....
just think over it guys is any reason so huge that you push yourself it to the realms darkness from where you yourself dont want to get out just because you think you can not be happy...?
