Notes have completely disappeared.

Updated my 2014 macbook pro to Catalina a few weeks ago. Woke up this morning and discovered my notes had completely disappeared. Years of important passwords, codes, reminders, etc. just gone. As if I had completely deleted them all last night. Is there any way to get them back? I have no iCloud backups and I don't understand what I'm supposed to do after searching the ~Library folder. There was seemingly no way to restore them once I got in the notes folder. Please let me know what to do I'm so screwed if I can't get my notes back this is ridiculous.
