Is this the one?
When I'm with you
I never have a problem when I'm with you
I'm really well-adjusted when I'm with you, with you, with you
When I'm with you
When I'm with you
I lose a lot of sleep when I'm with you
I meet a lot of people when I'm with you, with you, with you
When I'm with you
It's the break on the song
When I should say something special
But the pressure is on and I can't make up nothing special
Not when I'm with you
When I'm with you
I never feel like garbage when I'm with you
I almost feel normal when I'm with you, with you, with you
When I'm with you
When I'm with you
I'm always hot and bothered when I'm with you
I always need a shower when I'm with you, with you, with you
When I'm with you
It's the break on the song
When I should say something special
But the pressure is on and I can't make up nothing special
Not when I'm with you
When I'm with you
I never need a mirror when I'm with you
I don't care what I look like when I'm with you, with you, with you
When I'm with you
