"Dumb" lyrics

I know that it's been several weeks
Since I lay down and tried to sleep
But can't I see I'm doing something dumb

I can't get her off my mind
You know I've tried a thousand times
I tell myself I'm doing something dumb

Can't help but think about it
'Cause I can't live without it
Maybe I'll lose my mind again

I can't sleep and I can't eat
The beer just doesn't taste as sweet
And no one knows I'm doing something dumb

Can't help but think about it
'Cause I can't live without it
Maybe I'll lose my mind again

Pickin' up the telephone
I swear to god if she's not home
I'll kill myself I'm doing something dumb

I'm doing something dumb
I'm doing something dumb
I'm doing something dumb
