Have noticed we get really sad most times when we get hurt from people we love the more? Well it is normal to feel that way because you have created your happiness arround those people and that is the more reason you get pained when they hurt you.
Not that it is bad to find happiness in people , but it is better to create your happiness within yourself and focus less on the happiness you derive from people, the simple fact is that you feel unconditional hatred to a person you feel unconditional love too if the person wrongs you or hurt you, that why you need to build your own happiness within you.
Happiness is everywhere and in everything but the more you depend on people for it, the more you get hurt, this doesnt justify that people are bad, it is just how life is, we would definitely wrong ourselves no matter what. So why not create your own happiness within yourself and depend less on others for it.
Even a small things can be your happiness, just like mine. A cup of coffee make me smile. We only just need learn how to appreciate things.
