reading fiction makes me feel better and less alone, it helps me feel connected to other people who are like me. it has saved my life. it can open your mind to how other people think. it can teach you different worldviews and helps you become more empathetic. i'm only speaking for myself, but OP you're missing out. you just gotta find the right fiction that you like reading and relate to.
it's hard to say where to start, just start with a classic that seems curious and if you get bored then put it down and read something else. hemingway might be a good place to start — shorter, tight writing, not boring.
