Source of Happiness but Source of Pain

Day 40 

In life there are so many people that we intertwine, some with an impact bigger than others, some who touch our selves, a soul inside ourselves. Who soften the battles inside ourselves, people who brings us happinesss. But  life doesn't always fill our expectations, that then turn our source of happiness to our source of pain. That people made us so happy and so sad in the same time, that cause us to have a complete devastated. Then it comes back to us? To choose happiness or pain, whatever we think is possible it is, and as hard as we cover that we other happiness the truth is inside of us is mentally sick, that state of grey is what cause the pain to be even more painfull. So then we are given to choose happiness? Can't we just let it win over our ego?
