Why? I really don't understand

I dun understand why I was born in this family..

I dunno why I have a such ungrateful sister..

I dunno why I feel so bad to think bout it..

I dunno why I'm just as if the extra one in the family..

NO care..

NO love..

What I'd got all these while is being the meat of a burger(middle person)

NO benefits..

ONLY have sadness..

Darn upset,

Shedding tears all by myself..

Taking bus all by my one..

So ALONE...
