All my uploaded iCloud music is GONE! What Happened?!uploaded

I'm on garage band on a regular basis. Most of my music I uploaded to iCloud,and it get a iCloud logo in the corner and updates to the cloud whenever you use the music. But on Christmas Day, I was gonna go on the app. But because I had no wifi at the time, it displayed a text saying something like,"Cannot Download Songs from the cloud" I forgot what else said. After I pushed OK, I noticed all the music that was uploaded to the cloud was GONE! I also checked the storage and it said there's only 3.4MB from Garageband. I'm not sure is that's how much memory all that music took. It was about 8 original songs I made and one song take up a lot more when it's in GarageBand. Does anyone know if I can get my music back? Please reply if you have a solution as soon as possible. Thank you.
