Seeing your pain hurts me

I can't stand hurting you,
I really didn't mean to,
Seeing you upset makes me want to vomit,
All I want is for you to be happy,
I know that you don't mean to hurt me as much as you do,
And I forgive you,
But please just see,
I love you,
No one could replace you,
Mostly because you are you,
It was you that I fell for,
It is you that I love,
The sober you,
Not the drunk you or the high you,
The you that wrote me letters,
The you that could just cuddle with me,
But now you are gone,
I don't like the new you,
Yet I seem to have brought back the old you,
Please could you ever forgive me,
I really don't want to hurt you!!!!!!
