(5,611 posts)apart in terms of structure (and non-fiction obviously requires detailed research and documentation unless you are writing a memoir specifically -- or historical fiction). Have you worked on basics such as constructing effective dialogue for example? (I have taught creative writing and write fiction and academic work). Working on a novel is so very different -- you will need to consider narrative point of view, plot line, characters and characterization, dialogue, etc etc etc. You will need to craft a prose style that is suitable to the form.
If you are trying to write a memoir (like Girl, Interrupted) read as many examples as possible; also, look into the unique issues that accompany writing a memoir (including the names of real persons, or people who can quickly identify themselves, can be very risky for example -- also the names of real places). A memoir also needs to be constructed in a way that makes it interesting for readers OTHER THAN the writer herself/himself. This is much more tricky than it sounds.
There are a number of websites you can visit (creepypasta for horror and supernatural fiction for just one example) to share your writing with other aspiring writers. Honestly I would not worry about someone stealing your work.
