I'm sure it will turn up. I've figured out that you can never find something when you're looking for it. As soon as you wear yourself out and stop it turns up lol. Just like that magical disappearing tv remote
Just try to keep your spirits up because I know this is probably worrying you a ton. But worrying is like a rocking chair, it gives you something to do but it won't get you anywhere. I wish you the best of luck and I'm sure you'll find it very soon when you least expect it
