Heart with a shield

I have a heart with a shield
Where no one can get in
My love for you is never revealed
And never will dim

My heart feels like it`s closed tight
Never seeing this feeling
But knowing it is right
My heart never healing

I need to open it up and tell you how i feel
But how can i do that
When I don't want it to be real
I feel like i am in the war in combat

Yes I love you
I always will
But till i have the strength to tell you
Just until

I just want you to know that I miss you with all my heart
We are friends till the end I don't want anything more
Your such a sweetheart
But maybe I cant just ignore
