It's kind of a national holiday for Shawn Mendes fans Tuesday (April 14) -- as the singer's debut record, Handwritten, dropped at midnight. Sorry teachers, today is all about crying at one's desk while periodically falling asleep because our nights have been devoted to Shawn.

Many fans, also, decided to honor the day by hitting up Vine -- where our latest MTV Artist To Watch was discovered -- to upload six-second messages replete with heartfelt joy (wreathed with tears) over Handwritten's arrival.

Check out the most Vine-worthy fan reactions below -- and hit us up with your own at @MTVPop:

Some are lip-syncing it up...

... while others are showing off their vocal chops...

... there's also been some weeping (lots of weeping)...

... group sing-alongs are also a must...

... also, our HEARTS!

Did I mention tears?

Even cats are into it.

My precious...

Happy Handwritten Day! Now go take a nap.
