In appreciation of National Doctor's Day last week, I think that it's time we think about all of the amazing fictional doctors we've seen over the years. Whether they're coming in to save the day or breaking our hearts with an unforgettable exit, we could never forget them. In our minds, they're real doctors.

Here's a list of the best fictional doctors to date.

1. Dr. Derek Shepherd, "Grey's Anatomy"

I don't think that there was a dry eye in the place when we lost this beautiful doctor. The thought of never hearing him say that iconic sentence again breaks our hearts. Rest in peace, McDreamy.

2. Dr. Mindy Lahiri, "The Mindy Project"

How could we not love Mindy and her quirkiness?

3. Dr. Mark Sloan, "Grey's Anatomy"

After we got McDreamy, we were blessed with McSteamy. No one can deny that they liked watching this hunk work his plastic surgery madness. Of course, our hearts were shattered when we lost him too. Rest in paradise, McSteamy.

4. Dr. Remy Hadley, "House"

Dr. Hadley is one doctor who doesn't take BS from anyone. Her powerful stance is an inspiration to all women.

5. Dr. Jackson Avery, "Grey's Anatomy"

If we're having any plastic surgery, please let it be Dr. Avery operating on us!

6. Dr. Meredith Grey, "Grey's Anatomy"

She's the real OG of doctors. Can we be your person, Meredith?

7. Dr. Jack Shephard, "Lost"

If I'm going to be stranded on an island, I'm gonna want to be with the one and only Jack Shephard.

8. Dr. Cristina Yang, "Grey's Anatomy"

The sass and sarcasm are the best parts of the one and only Cristina Yang. We miss your rude comments and rare loving moments.

9. Dr. George O'Malley, "Grey's Anatomy"

If you didn't develop a soft spot for 007, you have no soul. George is the best friend who we've always wanted and we wish that he could come back.

10. Dr. Lexie Grey, "Grey's Anatomy"

She's the unknown half-sister of Meredith Grey. At first, we were sceptical of this one, but, as time went on, we learned to love her in the same way that we love Meredith.

11. Dr. Fitch Cooper, "Nurse Jackie"

He might have been a tool, but at least he has a heart of gold. Plus, he's not that bad to look at.

12. Dr. Izzy Stevens, "Grey's Anatomy"

We always wished that we could be her best friend.

13. Dr. Gregory House, "House"

He might be a complete jerk, but somehow that made us love him even more. No one can seem to resist a little bit of a bad boy.

14. Dr. Andrew DeLuca, "Grey's Anatomy"

He may only be an intern, but I think that it's safe to say that he's our favorite intern in the game.

15. Dr. Doug Ross, "ER"

It's an oldie, but a goodie.

16. Dr. Alex Karev, "Grey's Anatomy"

I think that everyone knows that under that tough exterior is a sensitive, caring guy and we can't help but love him for that.
