I miss the old you!

Without you my life is empty,
With you there is joy aplenty.
I miss the old you,
My feelings then you always knew.
Now you always seem sad,
I don't see the spark you always had.
Your smile makes my day the best,
I can then take any test.
My world you always are,
You may be near or far.
I love you till my last breath,
The only thing that can stop me is death!
