I am so sorry this has happened to you. I've had my share of accidental deleting of save/files, so I know just what you're going through. Did you create your original Sims in CAS? If so, you should have a copy of them in your My Library. Every time we create a Sim/family and place them in the game, it's automatically placed into our My Library, that you access through the Gallery. If you need to, take that break and when you come back, you can either look for that original Sim(s) and start again. Or create a brand new Sim, whatever you feel up to. I'm the Queen of Restarts. It can still be fun to play them over again.
