You should be able to access your Godaddy email account by going to this link.
https://sso.secureserver.net/
Then just enter your email address and password. If you forgot your password to your godaddy email account then click on the link I forgot and enter an email address that is separate from your godaddy email that you use for getting back into your godaddy email account.
If that doesn't work you might have to contact godaddy support and see if they can help you get back into your Godaddy email account.
