Changing Heart

I am given a heart filled with love,
Yet it gives me fear.
I am given a heart filled with hope,
Yet it gives me doubt.
I am given a heart filled with care,
Yet it gives me jealousy.
I am given a heart filled with joy,
Yet it gives me regret.

However, my heart is always changing;
with every passing time, it changes but it can never stop.
However, my heart is always truthful;
with every other hearts, it changes but it can never lie.
