I've been the lost
that was never found
^^
I love the reference but more importantly the way you personalised it to suit you! Effective way to lure the reader in! way to go :)

I've been the gone
that was never around
^^
Nice way to weave in the loneliness you feel, capturing your vulnerability so explicitly. I know what it feels like to be invisible, the feeling that if you were no longer there no one would even notice because they never did!

I've been the seen
who was always a ghost
^^
Wow you have extended this further, I like the use of ghost and how it is a rarity that people see you and if they do they dont believe their eyes, I like the linking and the flow!

I've been betrayed
by those I love most.
^^
Amazing!
This is my favourite stanza of the entire poem!
captivating and so heart felt, it always hurts double or even triple when hurt by those closest to you!

Amazing write!
