A Spontaneous Poem

Last night lingers on my mind
a black hole in my heart.

Any joy that might enter
is swallowed in the darkness of the thought
that I'm not meant for you.

But you see what I am. You saw what I was.

We all change throughout our lives,
keeping the base theme throughout,
overwritten by the constant change around us.

But the past is always there. Our true selves remain.

You have never forgotten. You always see the truth within me.
Or is it nostalgia?

I hope it's the truth. 
I could not bear it if this is how I truly am.
