i know who i am in my heart

i know who i am in my heart,
a loving mother,
a caring wife,
a trustworthy friend,
a believer,
and i feel blessed and talented
and loved and secure
and healthy and smart
and all of those types of things,
but my head tells me different
it says i am stupid,
and ugly
and diseased
and horrible
and a liar
and thief
and murderer
and untouchable
and unloveable
and somedays
i don't know if
my heart
or my head
holds the truth
