I'm Sorry

I'm sorry I can't be the person you want me to be
I'm sorry I'm not the girl you once knew
I'm sorry for acting like I was happy, when truthfully I was not
I'm sorry for telling lies and all the times I made you cry
I'm sorry I didn't give it my all
I'm sorry that my happiness didn't last that long
I'm sorry I gave up the fight
I'm sorry I ended it all tonight
