I would suggest that you write a few short stories about your hometown, people who live there, or some other topic, about which you know well. You can write about the real or imaginary persons, but the most important is that these people have a character in your story and that you use your own imagination. First when you have achieved skilfulness in writing short stories you can try writing a novel. You have written that you have read about 35 novels, but that is a small number, and the question is what kind of novel did your read? For example, reading romance or fantasy novels do not enrich your vocabulary in the same way as literary fiction does. Finally, writing novel is a complex and time-consuming work and many writers spend a year or even more until a novel is finished.
