There is a site I often frequent called Archive of Our Own. It is a combo Fan Fiction and Original fiction site with over 10+ million works on it and all totally free to read. I will often find solace in reading original works - some of which I am convinced could be published professionally - and sometimes I do some casual Fan Fiction reading of authors who are writing their perspectives on books, movies and TV shows.
I dabble read in all of them and many are outstanding. It's fun either way. It's a place that I can send my mind to when I need a distraction from the maelstrom that is my mind.
Naturally, some works are better than others, but they have a great search and filter tool that can be used. Readers can rate and review works as well. You don't have to be a member in order to read the stories, but it is easy to get added and it's totally free. Being a member allows one to bookmark your favorites and if you're a writer, even add your own. Some are works in progress and you can subscribe and be notified when the author posts a new chapter.
The site has been wonderful as there is so much to browse. I can also access on my phone on the go and I usually have several tabs open at once that I can switch between depending on what I'm reading at the time. My mind needs different things on different days and I often struggle to focus and concentrate - my eyes skipping all over the place. This site has so many writing genres, is a lot of fun to read and I'm usually able to find a good distraction. This site has been a lifesaver. Truly.
