Is good to wake up late

Accidently heard what you both talking about in the morning
I feel so dissapointed, not you both, but to myself
I knew I'm not a good child, I knew I'm useless, always make you all worry
I try to cover my emotion in front of you two, but i failed
I'm just superb silent today, I knew you all must curious about it although you all didnt ask

I couldnt get an answer how to be a good child, how to not make you all worry
Sometimes I'm so lazy to help you doing houseworks although seeing you already tired in doing such things
Sometimes I just ignore your busy-ness, I hiding in my room because I dont want to see your tired face, I feel so guilty when I see you
But, I cant hide from my heart, guilty seem likes to follow me, whenever I go

Night, I hurt myself accidently
I laughing, but my heart is bleeding, I know you'll think how useless I'm.............
