Does she sound familiar?

Does she sound familiar?

She has a huge heart and would bend over backwards to help someone.
She's loyal to the ones that mean something to her.
She smiles like she's never been hurt, but it happens more often than we realize.
She's fragile, it takes very little to hurt her; she takes everything to heart.
She's cautious and rarely lets people close to her.
She's more critical of herself than anyone else.
She'd rather look to the future than worry about the past.
She doesn't expect to be noticed, listened to or loved, although she deserves to be. 
She's not what you would expect but you will benefit the most by having her in your life.
