Unbiological sister

I was all alone
until she walked in
and made me believe that
she has got my back always

Soon we turned into friends
or shall I say more like sisters?
we spent half of our day together
and laughed all day over our inside jokes

Together we cried at daily soaps
and got in troubles for breaking rules
and how can I not mention that
we've always been partners in crime?

They tried breaking us many times
and none of their tricks worked
because we were stronger
our friendship was stronger

But one day death attacked her hard
she was only sixteen
and she was my best friend
(she still is)
she fought strong against her disease
but god needed this angel more than I did
and so she was gone
far-far away, to a better place

I miss her, i really do
but you know what I'm really hurt about?
I never got a chance to thank her,
thank her for being my unbiological sister and my best friend.
