my notes dissapered

Hey. So, two days ago, I was going to add something on my notes and guess what? 6 years worth of notes just dissappered. In my storage it says that I got 1GB of data but nothing appears on my notes app. I had everything on "my iphone" folder and now I don't have anything.

Does anyone been trought this? Does anyone nows the solution? Cause I'm here almost crying since I have there a lot of important and personal information.

(I guess it's time to start using the icloud folder)
