what she says:

i'm fine

what she means:

Be quiet Tiffany! Be quiet! Stop it! I have never in my life yelled at a girl like this. When my mother yells like this it's because she loves me. I was rooting for you, we were all rooting for you! How dare you! Learn something from this! When you go to bed at night, you lay there and you take responsibility for yourself because nobody's going to take responsibility for you. You rolling your eyes and you act like it's because you've heard it all before you don't know where the hell I come from, You have no idea what I've been through, but I'm not a victim; I grow from it and I learn. Take responsibility for yourself.
