Hi Honeyblue, and welcome to WW
You could have a look at the OU courses, which are all online, including forums so you can workshop work and interact with your fellow-students. There are short 12-week Level One courses in particular form - fiction, poetry etc., or a longer Level Two course, A215 which covers fiction, poetry and life writing, and is very good.

Your local FE college may well have 'start writing' courses, so that's a place too look too.
Another option which is a real kick-start, if you can clear a week, is an Arvon Foundation course, which are residential.

If you really feel you don't know where to start with getting words down you could start with a how-to book, and save the money for a course for when you feel you've got as far as you can on your own, and also when you know your own writerly self a bit more and can decide what kind of course would suit you best.
The textbook for the OU A215 course, Creative Writing edited by Linda Anderson, is available to buy and it's excellent. Another good one is The Creative Writing Coursebook ed. by Julia Bell and Paul Magrs. Another classic for getting going, though more about finding and shaping your own writing, and less about learning technique, is Dorothea Brande's Becoming a Writer.
Alternatively, just sit down and decide you're going to write a story. Think up a person - a character - with an urgent need or desire, start writing what they do to get that need/desire fulfilled, think up something which gets in the way, and write your way towards what happens when the need and the obstacle gets in the way... The story ends with that climax/crisis/clash, and some of the fallout from it, so that the reader understands what's changed from the beginning of the story.
Then join a suitable WW group, post the piece, and start looking at what others write - you'll learn as much from commenting on theirs as you will from their comments on yours.
Good luck!
