It's been a few weeks since you and your ex broke up. You somehow come across photos of the "good old times" between you two and start second guessing the reason you even broke up in the first place. You become immersed in those euphoric times and the next thing you know, you're crying because you feel as though you let the best thing in your life slip away.

But we all need those friends who somehow bring us back to reality and remind us how much better we are without that significant other. And who better to remind us of our spectacular selves than the relentless, tactless, and yet totally brilliant Cristina Yang.

First off, remember your ex could be as amazing as McDreamy, but if he puts you down and tries to eclipse your greatness, he is not worth your tears. You are the sun, shining brighter than ever with him out of your life.

For that moment when you start doubting your self worth because of all the things he said to you —don't let him get the best of you. Turn it into something powerful and shine on your own!

If he was one of those boys who kept putting you down and wouldn't let you have a good day, he sure as heck is not worth it! You deserve nothing less than the best and any guy who won't let you have that is out of your life for a reason.

To that boy who was clearly just trying to mess around with you, remember you are way more than your looks. You are a brilliant human and if he couldn't see that you were more than just a pretty face, he was blind.

When you feel like everything is crashing down, and you don't know why you are even second guessing your breakup, and you feel completely abnormal for wanting to hold on to the old times, don't sweat it. Nothing is normal to begin with, so don't think you're weird for having these feelings.

When you have an encounter with your ex and words seem to escape you and you can't process the moment, just do what Cristina and Meredith would do to drive their problems away.

Finally, you call your friends to help you with everything you're going through, and they try to cheer you up, but you are just in no mood to deal with the outside world. Yet they somehow get you to come out with them to get your mind off it.

When you feel ready to go out and take the world by storm, don't ever doubt yourself. You can look hot in anything. You look even better without him and you're about to show the world how amazing you are.

Of course, when you go out, it's normal if the only real interest you have is food. There is no shame in that. Food is the comfort that will never leave you dissatisfied and understands all of your true needs.

And when you decide after a long deliberation not to go out with your friends, you call your sister, your "person," the woman who will always know what to do even when you are at your worst. Sisters before misters, always.

Cristina Yang is the woman who seems to get life and will give it to us straight even when we don't want to hear it from anyone else. If a badass surgeon can get through her days of saving lives and all the crazy drama that happens at the Grey-Sloan Memorial Hospital, you can definitely get over this boy. You are 10 times better without him. Just ask Cristina.
