Am I amazing because I'm different, or am I amazing because I'm like her?

I love you with all of me, I have nothing left - So when you leave, you take all of me with you.

I swear, you set me free,
from all the pain I've felt,
to my heart, you hold the key.

My biggest fear is not being loved; I have so much love to give & i feel as though no one can ever return it properly. My only wish is that you change that for me.
