My advice would be just learning to step outside your own comfort zone IRL. The moment you can do that the walls will begin to come down. After this you can begin to explore the things that you relate to the best as you'll always find someone willing to listen to a good journey.

Also, it doesn't have to be long spills. I can tell you when I see someone has written something too long I don't read it unless it is something I need to see. All the best.
