There are so many different resources available on the internet, here is a collection of my favorites.

If you can, support your local bookstore! An indie bookstore, a Barnes & Noble, Books-a-Million or other applicable stores. I have an affiliate link at Bookshop.org, I earn a small commission if you decide to purchase any books from my storefront. I do highly recommend ordering books from Bookshop.org even if you do not purchase from my storefront as it supports local bookstores and you can select which bookstore you want to order from (there is even a map to find local stores).

Advice
Above all; read, listen, and watch. Inspiration and information is all around you. If one way of writing doesn't work for you, check out others and keep at it. No one can write the story the way you can, the one that is waiting inside.
If you can't write a novel, then try a short story or novella. If you can't start at the beginning, start at the scenes that do work for you. I have a small notebook that I carry around to jot down ideas in almost a bullet format. Those take root and grow, I'll add on to their page once something concrete appears for me.
Last piece of advice for now, work on what you love. Don't force yourself to write something that doesn't bring you passion (unless there is a real paycheck involved and its not a scam). We all have to pay the bills.
