Up all night, and i can't sleep.

I've been thinking about you all week.

I don't know what i'm gonna do if i can't stop thinking about you.

Thinking about you.

Thinking about you.

I don't know why i feel this way, but i feel like this every day.

I don't know what i'm gonna do if i can't stop thinking about you.

Thinking about you.

Thinking about you.
