Please Help Me Find This Book!

I started to read a book on Wattpad a while ago, then let my sister borrow my Wattpad to use and she deleted my library- deleting that book. I've read it over and over again and adore it, please help me find it! (Description in first chapter).
If you are in the same position and cannot find a book, message me with things in the book e.g. main characters, place the book was set, the kind of theme in the book and then a few sciences you can remember from the book and I will create another chapter in THIS book, in hope someone can find yours, thanks! -Elle xxx
