Longing

Have you ever felt a longing?
A longing for someone you can never have?
That person takes up everything in your heart and mind.
You wonder day and night whether you should come clean.
You think about them all the time.
You wonder if they think about you as much as you think about them.
You want to know how they feel about you.
Are you too weird, or too tall, or too fat to them?
Are you pretty enough for them?
Do they have a significant other?
Do they like someone else?
Have you spent all day wondering these things?
Have you ever felt a longing for something you know you can never have?
