What does ‘From Bridget to Carrie’ mean exactly?

I’ve gotten this question often & yes, I realize it’s a little confusing.

For years, Sex & the City has been my favorite show.  I have envied Carrie Bradshaw / Sarah Jessica Parker ever since I first saw it.  She lives the life I want when I finally graduate college and get my career started.  She lives in NYC, gets the guy, has a job she loves, wears amazing clothes & she’s fit.  I use her as inspiration.

Now, onto Bridget.  I couldn’t think of a fictional equivalent (CB is fictional, therefore I needed another fictional person) to someone overweight & unhappy, then I remembered… Bridget Jones.  Albeit, she weighs 140lbs & is ‘overweight,’ which to me is a little ridiculous.  

I want to go from sad Bridget to my own personal Carrie.  To be happy.  With my self, with my body, with my life.
