Goodbye

"The dictionary defines grief as keen mental suffering or distress over affliction or loss; sharp sorrow; painful regret. As surgeons, as scientists, we’re taught to learn from and rely on books, on definitions, on definitives. But in life, strict definitions rarely apply. In life, grief can look like a lot of things that bear little resemblance to sharp sorrow."

- Meredith Grey

"Grief may be a thing we all have in common, but it looks different on everyone."

- Lexie Grey

"It isn’t just death we have to grieve. It’s life. It’s loss. It’s change."

- Mark Sloan

"And when we wonder why it has to suck so much sometimes, has to hurt so bad. The thing we gotta try to remember is that it can turn on a dime."

- Alex Karev

"That’s how you stay alive. When it hurts so much you can’t breathe, that’s how you survive."

- Izzie Stevens

"By remembering that one day, somehow, impossibly, you won’t feel this way. It won’t hurt this much."

- Derek Shepherd

"Grief comes in its own time for everyone, in its own way."

- Miranda Bailey

"So the best we can do, the best anyone can do, is try for honesty."

- Owen Hunt

"The really crappy thing, the very worst part of grief is that you can’t control it."

- Meredith Grey

"The best we can do is try to let ourselves feel it when it comes."

- Arizona Robbins

"And let it go when we can."

- Callie Torres

"The very worst part is that the minute you think you’re past it, it starts all over again."

- Meredith Grey

"And always, every time, it takes your breath away."

- Cristina Yang

"There are five stages of grief. They look different on all of us, but there are always five."

- Meredith Grey

"Denial."

- Alex Karev

"Anger."

- Derek Sheppherd

"Bargaining."

- Miranda Bailey

"Depression."

- Lexie Grey

"Acceptance."

- Richard Webber

'''Time has passed... Everyone is struggling after losing one of their own and are turning to any distraction they can find. Meredith and Derek seem to be consummating their marriage anywhere and everywhere, while Cristina and Owen have been instructed to abstain from sex by Dr. Wyatt.''' thumb|300px|right thumb|300px|right

Quotes

 * Alex: [to Izzie] You died in my arms. You died in my arms, you freakin' died and then you left instructions that i wasn't allowed to save your life. You wanna know what I'm scared of? I'm scared of everything! I'm scared to move! I'm scared to breathe! I'm scared to touch you! I can't lose you. I won't survive. And that's your fault. You made me love you, you made me let you in, and then you freakin' die in my arms!
