Grey's Anatomy Quotes

There's a reason I said I'd be happy alone. It wasn't 'cause I thought I'd be happy alone. It was because I thought if I loved someone and then it fell apart, I might not make it. It's easier to be alone, because what if you learn that you need love and you don't have it? What if you like it and lean on it? What if you shape your life around it and then it falls apart? Can you even survive that kind of pain? Losing love is like organ damage. It's like dying. The only difference is death ends. This? It could go on forever.

Meredith

You think that true love is the only thing that can crush your heart; that will take your life and light it up or destroy it. Then you become a mother.

Meredith
