How can I get my motivation back after losing my art?

My phone just broke down. We managed to get it back to work, but all my data is gone. I lost a portion of my artwork, including all the character sketches for my story. And I’m currently not happy. I have been feeling depressed recently, thinking about how all my hard work is now gone. I want to get back to work on my sketches and comic, but thinking about what happened just makes me feel so discouraged. I feel like I can never create again. Is there any way I can bounce back?
