Under Lock and Key

If you read this, I really hope you like it, sorry I don't really want to explain myself!

Untold stories weigh on my heart
Constantly closing the door in your face
Too scared to share my thoughts and feelings
You try so hard to force yourself in
But I'm not the open book you wish me to be
I must keep things locked in for myself
You must understand, I don't mean to seal myself off
I have my secrets, as I'm sure you have yours
But mine must remain under lock and key
Wish I had the courage to share
But for me to stay afloat on this emotional sea
I must keep my secret wishes and desires
Closed off from you and everyone else
Forever they shall remain buried deep inside
For it's what will always keep you from breaking down my door
