I only cause pain

The only thing I seem to do
Is cause you worry and pain
Nothing I ever do is right
My life is full of shame

Can't you see how hard I try
To get through this mess
Why do you always sigh
And say I cause you stress

This illness is not my fault
It's out of my control
You make me really want to revolt
And say, screw it all

You're turning me against myself
Making me believe
That all of this is my fault
That i had better leave

You shout when i try to die
I pain you when i stay
Around me, chains you tie
So I can't get away

People tell me how you feel
That you wasted your life
Your happiness do i steal
Should i use the knife?

You say I'm in my own head
That all i care for is me
When i would do anything instead
To not let this be

The only thing i ever want
Is to see you smile
To see you happy again
If just for a short while

But i don't seem to make you smile
Not a single trace
I would walk a thousand miles
Not to be a disgrace

I don't bring you anything but down
A simple waste of space
Please, i don't want you to drown
So i will leave this place
