All Sims and Households GONE :(

Hello everyone, 

I have no idea what to do, I'm not even really sure what I did wrong. For starters I am not a technology person like that whatsoever, and basically my Sims4 game had put furniture for all my houses inside my sims inventories. When I would try to place the items back in my game it would say "SCRIPT CALL FAIL" and after some further research I think (heavy on the I think) one of my mods or CC items was broken or outdated, however, I do not know which one it was. I watched a YouTube tutorial on how to fix that problem and I thought I did it correctly but I guess I did not, because when I opened my game back up it was showing as if I never even played before, and I have 701 hrs. of game time listed in my EA account. It wouldn't even give me the option to load an old game or anything my only option was "New Game." I've tried everything to get my sims back and all my game data, the mods and everything is still on my MacBook Air, they even show up in the clothing and hair/makeup section in the game still, all of the mods stuff is still there, but my sims and households are JUST NOT THEY ARE GONE :( Idk what to do at this point, and I got directed here after speaking to someone through EA Post-Chat. Does anybody know what I could've done wrong or have any advice on what I should do, any tips? Really anything at all :( Please, I've spent SO much money on this game, I've paid for 11 different add on's and I have spent so much time on over 80 sims and so many houses and rooms, so much detail and dedication is just all gone and I don't even wanna play anymore because starting alllll over is not even worth everything I accomplished and had set up with my original sims, their lives, homes, and just everything.
