Diagnoses: Bieber fever
Symptoms: obsessive thoughts of Justin Bieber, stroke, heart attack, and seizure possibilities if meeting him, crying hysterically, screaming at a shrieking tone, fainting, and falling in love. Falling in love is most likely permanent and irreversible.
If you have heart conditions or medical issues, you should consult with your doctor before watching him on TV, looking at a picture of him, or meeting him in person. It is most common in young girls.
So far this fever is incurable.
