it's possible to earn a living as a writer, Della Galton mentioned teaching at a Woman's Weekly writing workshop. Currently these are full, but they've proved so popular I think they're likely to run more in the future. (If you can't get on a course and would like some help with your writing, you might find this book useful.)
Of course they include inspiring teaching and the chance to meet other writers, but there's a benefit you may not be aware of. Della tells me that attending one of the workshops allows the writer to submit their fiction to Woman's Weekly. Currently, unless you're already on the list of approved contributors (you'll know if you are) this is the only way to have your fiction considered for Woman's Weekly.
See here for details of magazines which consider work by writers, whether or not they've had previous publishing success.
