The 20-year-old pop star first premiered the video on Twitter to her over 15 million followers on Wednesday.
The music video follows a young couple, whose love was suddenly interrupted after the male character was sent to war.
The singer sent out another tweet, where she dedicated the video to the troops.
According to MTV, Lovato co-directed the video with Ryan Pallotta. This is the first time the singer has taken on a directing role, which is something she's wanted to do since childhood.
"I always wanted to do it when I was younger, then I just had the opportunity this time and I was like, 'Oh my god, I have to take advantage of this,'" Lovato told MTV.
I dedicate my video to all of the troops, anyone who has passed away over seas and to this INCREDIBLE country that I'm so thankful 4.. 🇺🇸❤— demetria lovato (@ddlovato) July 17, 2013
