How do I recover deleted Apple Music library

I have had my music library deleted and my playlists are all empty, I have tried to find a way around it for months but to no avail, “ Turn On Sync” has always being turned on. My subscription went out and I subscribed after a few weeks and this happened.

There has to be a way Apple can get my music back. It’s well over 5000 songs for over 10 years.

There is a new apple feature that is called favorites, the songs I had clicked “ LOVE” on in previous here appear to fall in that and it automatically added to my playlist. My other playlists are empty also.
