All I can say is sorry, even if I'm not the one who messed up.I'm sorry I'm not good enough.
I'm sorry I'm useless.
I'm sorry I'm worthless.
I'm sorry you broke my heart.
I'm sorry I trusted you.
I'm sorry I'm not what you want.
I'm sorry I'm not like them.
I'm sorry for making you leave.
I'm sorry for always getting sad when you didn't text back.
I'm sorry for getting jealous.
I'm sorry I fell in love with you.
I'm sorry for screwing us up.
In the end, all I can say is:
I'm sorry for being me.
