today was the worst

i saw myself crying inside, no one can see it, neither do i. i became silent, day after day i spent my whole day sitting in the corner. i feel so unmotivated, i felt so much pain without knowing the reason. i saw a black shadow laughing at my worst days, while i beg for the answer why i have to feel this. i feel like everything’s change, i couldn’t be more happy even in just for a day. i don't know what’s the point of being unhappy, why do i need to feel this?
