I'm so sorry, that is extremely frustrating and demoralizing to lose nearly everything of a project. Sure you have the idea of what was there but you have to recreate it or if you're lucky pay a company to recover. I doubt anyone here will blame you for whatever decision you make, I say do what makes you happy and fulfilled and whether that is to close this chapter and start a new one or not we'll still be here, take all the time you want. Hopefully something cheers you guys up soon.
