I can help you cancel your domain styleworthwhileblog.com if you'd like. However, I just want to make sure you know what will happen to your cancelled domain.
Canceling your domain means you completely give up ownership of the domain. There is no guarantee the domain will become available to re-register after cancellation. If you think you might ever want to use this domain again, I recommend keeping it.
You are also welcome to register more than one domain for your blog. If you want to register a second domain, you can do that and just keep this domain around until it expires. I can give you more information about that if you have any questions.
If you're sure you'd like to completely cancel your ownership of the domain styleworthwhileblog.com, please reply to this thread to confirm and I can take care of that for you.
