Do you know that sadness slows down life?

I know now... When you are sad life goes slowly. It is like everything around you passes in slow motion. You lose your enthusiasm and will to smile. You feel lost and you dont know where you are going. Your feet can hardly carry you because you are heavier with the weight of your sadness. You walk so slowly, your eyes on the ground. Everything that makes you smile can't make you smile anymore. Like a nice car passing by, a small kid's three wheel cycle parked outside house, a beautiful flower growing by sideroad, an only litten window in a big building... maybe you don't notice them anymore. Or you notice them but you forget that they make you smile. It is even harder when you are with other people becuase they expect you to be happy and you have to put a forced fake smile on your face which makes you feel sad even more. You forget where you put your keys or what you just read in your book. You feel tired without reason and want to sit down and cry everything out. Your tears betray you at the nights or on the road or in the public. You look but you can't see. It is like some unknown clouds curtain your eyes. And then the only consolation is to think that everything could have been worse...
