why

hi , today i heard the song of nelly furtado called "all good things come to the end".she has right through my experience , always good things in your life is short.why?why the worst things is longer than the good thing.it's just as dream.why when we enjoy a moment it ends so quickly.it's just emotional or it's real.sometimes , i feel afraid to be happy cause the feeling after the end of happiness is so hard so , i am afraid to lose this happiness.but i start to enjoy my happiness whithout thinking what come after.when i am with my family,usually,i think one day i will miss my family cause we will die.or some of us will die and i will miss to be with him or her.it will become a souvenir.so , i stop enjoying my time.now, i try not to think like this cause it' avoid me to enjoy my moments that will make me feel regret cause i will punish myself of losing the chance to enjoy my time.i try my best not to follow this bad feelings.today is sunny.thank god
