Hey there CaitlinNesci! Welcome to the Spotify Community.
I know I'm not Richard, xD, but I'd like to help you out with your situation, :).
You'll be glad to know that Spotify now allows you to register for its services using an e-mail address that isn't necessarily tied to your Facebook account. You can create a username and password and use that to use Spotify moving forward. If you'd like to transfer your playlists over from your old account to your new account, you can fill out a form at this link. If you get an automated response, you can just respond back to the e-mail and one of the Spotify professional staff will get back to you.
I hope this has helped you and I do sincerely hope you continue to thoroughly enjoy the Spotify streaming service. :).
