you could say that her smile is so vibrant that the sun at day, the moon at night can’t compare; that her laugh is addicting like a drug, so addicting, the withdrawal from it kills.
you could say that her character is so cheerful that a cheerleader is seen only as content; that her personality is sweet like a slice of cherry pie, so sweet, the grace is indulged until evaporated.
you could say that her bones are so selfless that the tree’s energy exertion is used for personal growth; that her voice is gentle like a mother’s kiss, so gentle, the wrapped insults unravel as compliments.
she could say something, though mental illness is self diagnosed and depression is an exaggeration of being sad.
