Accidently Deleted Household!

Hello. I had spent hours on making the perfect household and I was finally happy with how they turned out. I started a game but accidentally chose the wrong lot size. I deleted my game so I could start a new one and get the correct lot this time. Although, when I deleted the game itself, now I can't find my household... I did save my household to my library. I totally spaced out saving my "saves" to a backup as well. I'm crushed, is there any way I can restore them? And also, I had deleted previous games with that household and everything was fine. Thank you!
