If you're like me, from about 2008 to 2011, you were a hardcore Bieber fan, and then decided you were too mature to have a crush on the Biebs. But then his new album came out, and you questioned why you ever made the decision to be mature. You went through Bieber Fever again, and twice as hard. Here are the common symptoms of The Fever:

1. The first time you heard "Sorry" you tried to sit there and pretend like you didn't want to get up and dance like your middle school self.

2. You saw his Calvin Klein photos and had hot flashes.

3. You stalked all of the girls that he posted pictures of on Instagram.

4. You turned on Twitter notifications for every time that he tweets.

5. You made your friends try and recreate the dance video to "Sorry."

6. You listened to all of his old albums and probably cried.

7. You also probably re-watched all of his videos on YouTube.

8. Any time you went to a party and a song from his new album came on, you screamed and brought your dancing skills to a new level.

9. You created a face in a hole with a picture of him, like this:

10. When guys finally admit that he is talented you get really defensive and make them feel bad about taking so long to figure that out.

11. You're still waiting for the day that Ellen surprises you with Justin Bieber because you're his biggest fan. Obviously.

12. This will always be relevant and basically sums up all feelings that could ever exist for The Biebs.
