The reason why

She didn't want to be herself anymore.

She was ashamed of her body, the way she spoke, the way she moved and the way she looked.

She wanted to disappear because she thought she deserved it.

Because of the sins she had commited

Because of the amount of people she had hurt in her life.

And if that weren't enough, she felt like she was hurting people e v e r y d a y.

She hated herself for it.

Even if there were days when she tought she truly liked herself,

it was just an illusion.

It was only a matter of time before she did like being mean ( even by accident).

She accepted other people's mistakes.

She couldn't accept her own though.

She interpreted them as the end of the world.

Maybe that's why she did the same with her life.
