Lovesick

From what I'm told, this happens all the time
You fall in love, she's always on your mind
And I can't sit still, I feel like a little child
I don't wanna come back down
I don't wanna come back down
Please don't let me burnout
I watch the clock, so my breath stays in time
If I called you mine, would that be out of line?
And I feel like I'm in love for the first time
I don't wanna come back down
I don't wanna come back down
Please don't let me burnout
