Life really is such a terrible, unfair concept where everything is determined by luck and chance and where factors outside of our control can cause us to suffer to such great extents. Your frustration towards life is understandable, I've always seen life itself as being the problem and have had a strong dislike towards it. This is why the thought of suicide has always appealed to me so much as it's the one thing that I can control, when I leave this world. So much in this life is out of our control, it isn't as though any of us asked to be here in the first place to endure this life.
