Garageband files disappeared from my phone

I have numerous projects I started in garageband over the span of almost a year. My storage had been full for a while and I decided to sign into my old Apple ID. When I signed back into the previous Apple ID all my garageband projects were gone. Only about 8 projects which I restored from iCloud when I got a new phone are there. I checked iCloud and the lost projects are not there. I am extremely distressed as these projects are months of work. Please help me find my files
