I'm sorry that you've seen me broken.
I'm sorry that I couldn't control my emotions.
I'm sorry that I couldn't put yourself above my feelings.
I'm sorry for showing you fear.
I'm sorry you ever had to worry about me.
I'm sorry that you ever had to comfort me.
I'm sorry that I'm not as strong as you need me to be.
I'm sorry you felt that you needed to take care of me.
I'm sorry that you thought that you had to check on me at night.
I'm sorry that you ever had to worry about what tomorrow would bring.
I'm if you ever thought that it would be the last time you would ever see me.
