Something is wrong in my brain

This song has been stuck in my head, see if you can't figure out why I'm worried about myself:

it's cold outside
Time for you to go out go out into the world
it's cold outside
Turn the lights up over every boy and every girl
it's cold outside
One last call for alcohol so finish your whiskey or beer
Closing time
You don't have to go home but you can't stay here

I really can't stay
I know who I want to take me home
I've got to go away
I know who I want to take me home
This evening has been
I know who I want to take me home
So very nice
I know who I want to take me home
i simply must go
I know who I want to take me home
the answer is no
I know who I want to take me home
your welcome has been
I know who I want to take me home
so nice and warm
I know who I want to take me home

it's cold outside
Every new beginning comes from some other beginning's end
