RSS feed URL does not seem to exist on this earth

I have spent several hours trying to find the correct RSS url for my WP blog, which is set up through my website. Feedburner says it is not valid, I can’t find anything on the wordpress site to help when I try to just add the RSS widget, and I have googled until I am blue in the face (over 3 hours) and tried everything I found suggested for entering a valid url. Absolutely nothing has worked. I see by forums here and questions posed on other sites that this must be a problem for a gazillion people. My blog address is http://bittersweet-hollow.com/blog and while I do not intend to sound grumpy, I am. Thanks for anyone’s help.
