honestly man,i feel you as if there's nothing left from you to stay in this kind of world we live in....
now,take a deep breath and ask yourself is this really what i want to do,end my life? aren't you're lucky that u were here,there is a purpose for that.
whatever problems u are encountering now try to analyze each of it,i just don't get it,why it takes 3 months for u to decide this... :(
try to visit any Psychiatrist available here in Doha.
