Just let me know

Whenever I'm around you, I feel like life's complete. 
I don't know what to say, But you make my heart beat. 
I'm scared to say hello, But it hurts to say good-bye. 
I've been hurt before, Now I feel like loves just a lie. 
I'm falling really hard, There's no stopping me this time. 
I think you're there to catch me, To finally let me shine. 
I lose my voice, When your nearby. 
I'm scared to mess things up
I'm scared you'll say good-bye. 
I'm sorry if I'm wrong, When it comes to liking you. 
Just let me know, I don't want to be hurt by you
