Youre doing my head in

Why can't I get you out of my head?
Why can't you just disappear?
What have I ever done to you?
That was so bad
You had to treat me like this
Youre messing with my head
Your putting things in there
That I dont want
Your making me doubt myself
And what I want
Why are you doing this?
I know what you are
I know you will always be the same
I realise that
But still
The little things you do
They still get to me
They still drag me down
Youre doing my head in
You know you are
