You could always try reading non-fiction books that aren't "made up." There are all sorts of non-fiction books out there. Biographies, autobiographies, and memoirs. Books on every subject from history to psychology to science to art to sports. So, whatever topic interests you, you can find non-fiction books about it.

As to your preference, there are plenty of readers who prefer non-fiction to fiction, plenty of readers who prefer fiction to non-fiction, and plenty of readers who enjoy both. All are just a matter of taste. None is really weird.
