Caution! Jonas Brothers tearjerker!

Today is World Diabetes Day. If there's one celebrity who has been front and center for raising awareness about diabetes, it is Nick Jonas himself. Nick wrote the song, "A Little Bit Longer," about his experience struggling with the disease, and ultimately staying on top of it. He's been known to break down and cry while performing this song live, so don't say we didn't warn you! The song is beautiful!

And if that's not enough, Nick has recorded a PSA for the Juvenile Diabetes Research Foundation. He says that he's one of three million Americans who have been diagnosed with type 1 diabetes. "If you have a diabetes, you're not alone," Nick says. Check out the inspiring video below.

If Nick has motivated you to help out, find out what you can do to raise awareness about diabetes.
