My entire library is wiped

So I play The Sims on PlayStation. I was trying to take my sim and make her base game compatible so that way I could upload her without having to fuss about people not being able to download her because of too many packs.

I was in a save file and specifically change Sim mode, when I realized I couldn't save the Sim to my library. It said my library was full so I started deleting a bunch of EA builds that I never used. And then it said it couldn't access the proper servers to save anything to my library. 

So I figured it couldn't hurt to try and restart the game, but it buffered the closing screen wouldn't go away and there was no way to exit out of it so I had to turn the entire PlayStation off. When I turned it back on everything seemed to be fine I went back into the safe and successfully managed to save the Sim to my library. 

However my entire library was gone, my builds, households, but most of all I made picture packs for my Sims. Taking photos in The Sims is truly the worst so I dedicated a save slot to taking pictures I then put all the pictures in a room and save that. I never published them because they were for my own decor use. And I constantly replaced that saved file with other picture saves thinking they were safe in my library.

Because I never encountered an actual error code that shut the game down I can't restore that version of the game to try and see if my library is on it. And I did try to restore the license as someone else said on here but it seemed to corrupt my save file as it removed anything that wasn't base game CAS from my sim. I did eventually manage to fix it by trying it again.

Genuinely don't know what to do I just want my photos back fml
