Jello

You can poke and poke at jello, watching it bounce back. You can keep poking and prodding. Its amusing, but as you keep doing it and wears. Or perhaps its your nail accidently stabs into it. Then there is a wound in your jello, and it can't be heeled. And its all your fault. Or maybe it's the jello's fault, for having such unpredictable properties.
Ella Mason is a young girl who...can be considered a bit bipolar at times. But she recovers. And everything, every person, everyone that's ever hurt her, she just bounces back. She keeps her unpredictable mood swings to herself, and sucks it up. It is her fault after all. Everything is. But one day, everything changes, and Ella breaks.
