there is always bad moments

lately i've been feeling like there is no tomorrow, like my world is falling down and i feel like i'm a worthless piece of trash, then i wonder why am i such a rotten apple falling from a tree yet not quite landing. is there any hope around that keeps me up?what is it how come i can't see it where is that hope? maybe someday i'll be able to fly and dream on in a world that means joy and where there is no pain and no worries. but until that day comes i still fee like that piece of worthless trash
