Visit google.com/account in a browser. Google has linked every YouTube account with a Google+ account. The only way to delete your YouTube account is to delete the Google+ profile associated with it.  Deleting your Google+ account will not affect other Google products such as Gmail or Drive. Your emails and stored files will not be deleted. All photos uploaded to Google+ will still be accessible via Picasa. You will not lose your contacts, though they will no longer be organized by Circles. You will not lose any Google+ pages you own or manage. You will lose access to your Google+ profile and all of your +1s.    Your Google+ profile will be deleted, which means your YouTube channel will be deleted as well. Your comments and messages will be permanently deleted.
