Royally screwed up your life

I'm sorry for all the pain I've caused
I'm sorry for all the trouble
I wont cause anymore, I promise
I never wanted to hurt you
I never wanted you to cry
I never wanted to see your tears
I never wanted you to die inside
But Instead I went on
I didn't stop
I just kept going
Not caring how many people it would hurt
But now that I know what its like to lose a true best friend,
A sister and a person who understood me better than I understood myself
I know that I was wrong
I'm sorry for all the pain
All the trouble and all the shame
All the hurt and all the tears
All the fighting and all the fears
And your nightmares I can't cure
But for now a "sorry" is all I have
Though I know I've betrayed you
More than a sorry can fix
So I wont cause anymore pain, no more trouble or tears
I'll leave you be if thats your wish....
