I think I would replace it (at my own expense) with a cheaper version (if that's possible). In that way, you will have something similar to use (and can relieve your mind a bit), until the "real" item turns up. You may very well have just hidden it away for safe keeping and will find it someday. If it never turns up, then start saving to replace the original thing. I'm sorry this has hit you so hard. Maybe planning to replace it someday will help.
