Don't look beyond the mirror. You won't like what you see.
If you do, please remember this: she can only hurt you if you let her. Don't listen to her lies, even if it's the truth. Don't just stand there as she tells you how you are worthless, how you are broken and ugly and unloved.
Don't listen to her sweet voice as she tells you that she can love you, that she can make you beautiful and make you shine with such light.
Don't trust a word she says. Don't take her hand. Don't give in. She will take you and she will change you and you will become what's on the other side of the mirror. She will take you to her desert garden and she will make you into her own image, a cold, unfeeling temptress. A snake in the garden.
So don't look beyond the mirror. You won't like what you see.
