The rise and fall of emotions

Sometimes I wish I could understand why people have emotions. To cheer up life some would say. But what about bad emotions? Like being upset, depress, fear, angry, disappointed, jealous, hatred? what can all these do to us? It just bring the atmosphere down. And sometimes I wish I could understand why we felt indifferent all of a sudden and you just feel bad about everything but still dun wish to affect the people around you. So in the end you're just grieving within yourself.

The thing is this sort of feeling fades over time and in another few days time you start to feel happy and got excited to do something extreme out of a sudden. You just feel good out of the blue. Everything began to turn out right and you're so hyped up to do anything you're asked. Until the moment you're hit by bad comments and someone throwing rumours at you, that you finally realised having emotions and feelings are just so tiring and complicated. hmm...
