what's wrong with her?

i don't know what i feel right now
everything seems not right
i feel as if i wanna cry
but i don't know why
something is missing inside of me
everything that i did will end up wrong
people see a girl that is always happy and does not seem to have any problem in her life
that is what they see
but inside of the girl
no one really knows
what's wrong with her
what does she wants
why isn't she happy
that a question that no one will ever know
