Brenda Ueland's book is time-honored sound advice. It was published in the 1930s or something,
decades before e-books or audiobooks or all these fancy whatchamacallits came about. Also have a look at
Bird By Bird by Anne Lamott;
Writing Down The Bones by Natalie Goldberg,
The War of Art by Steven Pressfield, and perhaps the go-to tome for overcoming creative struggles,
The Artist's Way by Julia Cameron.
On Writing by Stephen King is a good one too; I mean, it's Stephen King, and he's had a pretty good run of publishing success, wouldn't you say?
I don't go out much so I don't have a chance to go to the library. I live in a high-crime area and don't have a car, so walking there is a definite no-go because the 'rents can't afford to have me on the ins. policy for the family chuck wagon yet, which means I have to keep my reading list as just a list for right now. But one of the things I've found very insightful is reading about some of the science behind creativity -- I know, it sounds cold and in fact quite the oxymoron, but I guess the inner geek (the antithesis of a creative muse, I would think) has latched onto an interest in this whole thing. Magical mechanics is how I think of it. Recommendations include
The Midnight Disease, by Alice Flaherty, M.D., a neuroscientist at Mass. General Hospital who
herself had a mental breakdown following the miscarriage of both her twins.

She is also a diagnosed manic-depressive who, during her manic stages, encounters "fits" of
hypergraphia, or the compulsion to write. (Sort of a Nanowrimo syndrome, only it's almost more like Nanowri
minute.) She wrote the book in a relatively short amount of time -- I don't know exactly how short -- and from it developed a program at Mass. General using an experimental but non-invasive treatment for clinical depression and schizophrenia to aid in the treatment of creative blocks (which are often brought about by mental fatigues or emotional illnesses).
I myself don't doubt that I have a veritable rat's nest of emotional/mental knots to untangle that's causing my blockages right now, what with the abuse in my family and being bullied all throughout school and witnessing a lot of the things that I've seen. So I've been looking into a lot of these books about the correlation between creativity and mental illness/emotional traumas and even reading some online stuff about it. Also on my list are
Touched By Fire by Kay Redfield Jamison and
The Highly Sensitive Person by Elaine Aron. I need to get back to reading more (and maybe find a decent doc of my own) before I can really go full-swing into writing again. (And maybe find a way to disconnect from the damn internet.)
But I second (third? Fourth?) the notion to just take a break for a little while and return when you're ready. I always feel "mocked" by days going by and my not having written anything worthwhile, in fact not anything at all besides my various diatribes online. For me personally, I think I'm one of those who can't restrict myself to just one creative outlet; practically anything you do can become an "art" form in its own right, so if you like gardening or painting or cooking or some other activity, do that, and give the muse a little breather. Remember what the man from Chicago said? No, not the president, I mean Peter Cetera.
"Everybody needs a little time away, a holiday, from each other."
Even your muse needs a little vay-kay, far away, from the work that you both love...
