Because it is all in the heart. It would be best if you understand...
Life is a mixture of everything. Sadness, happiness, loneliness and lots of other emotions. Everyone just take things by their stride.
Decision making is like an everyday thing, but it ain't easy to know what is the right thing to do every now and then. But even though it is difficult, it definitely does not mean that we can't get things right.
Hurting yourself and others is definitely not the way. People around you feels the pain, agony and the helplessness. And ending life is foolish. No one should ever do that.
I really hope things would be good, only then I will feel happier.
