How to restore local music files after syncing with Apple music?

After subscribing to Apple Music and syncing my library, over 20,000 local music files in my iTunes media folder have vanished. The iTunes app I was using to manage my music library only has podcasts and audiobooks -- no music. I see all my missing music in the cloud library and need to know the process of getting those files back on my computer. I'm still subscribed to Apple Music and plan on canceling as soon as I get my personal music library back in my possession.

I have done the following (per turingtest2 advice) but it did not restore my music:

"removed any of the apps Apple Music, Apple TV, and Apple devices, you are signed into your Apple ID in iTunes, your computer is authorized to your Apple ID, in iTunes under Edit > Preferences > General you have iCloud Music Library ticked, you have selected Music from the drop down list of media types, and View > All Music is ticked. You should now see your library, with any content that you have in the cloud and not stored locally, available to be right-clicked with a download option. You can select batches of tracks or albums to download. You also make a smart playlist that shows music that is not on this computer in order to highlight the content that needs to be downloaded."

PLEASE PLEASE PLEASE help! Apple customer service has been awful and worthless.
