Keep me Guessing

I can see your lips moving,
Yet I don't hear a sound.
All my thoughts just scramble,
Whenever you come around.

I try to steady myself,
And make sense of what you say.
But I lose all of my control,
And my mind just draws a blank.

Jealously runs through my veins,
It's a new and irrational feeling for me.
You make my heart race,
And make my knees go completely weak.

It's so exciting yet so scary,
Something I've never felt before.
Please just tell me how you're feeling;
Don't keep my guessing anymore.
