Missing Folder

I have a Dropbox Professional account. Last week I was reorganizing my folders and files, spending a lot of thoughtful time doing so. Two days ago, I realized that one folder is now completely missing, and with it, all its files. This was not a shared folder. I looked on the deleted list and the folder does not show up on the deleted list, nor do any of its files. I searched for several documents by their specific names, and nothing turned up. It is as though the folder and its contents never existed. The only thing I eventually found that showed that my folder ever existed was in my desktop recycle bin... the folder was there. I restored it, but only a few files were in it. The path showed it was (or at least had been) in dropbox. I know it's a holiday for many of us, and I will ask for online help on Monday, but I thought I'd reach out to this community because I'm trying to not freak out.
