Hey @Yourbestdayever, thanks for checking in with us.
At first, if you find that computer folders (such as your Documents, Downloads, and Desktop) were added to your Dropbox folder, don't delete the folders or the account itself.
Instead, turn the computer backup feature off and then move the files back to their original locations.
Once you do that, you can then delete your Dropbox account, if you still want to.
You can find the relevant steps and what happens when you delete your account, here.
Let me know if you have any other questions, cheers!
