sims wasn't loading and tried fixing it now everything is gone

Hi so i play sims 4 on my Macbook air. Had a problem yesterday where i saved my game and tried starting it (closed it to update it). After i opened it when i chose load game, the household that i last played on, it would just load for a second and then crash. I tried in the origin app to repair the game and start it again but it didn't work. I tried starting the game from my desk and that didnt work so what i ended up doing was following the sims 4 EA help on how to restore a previous saved game. After i did that and loaded the household save everything was gone, all my custom houses and buildings in the worlds i have. I panicked and put the chosen save file back into the electronic arts saves file and loaded it again and now its back to default. Im legit panicking that everything's gone and i don't know what to do to fix and get back everything. By the way i have no mods or CC installed.
