My *personal* fandom journey, when I really made it my own (you know, just like a kid has to accept their parents religious beliefs as their own eventually) was with a certain book series that shall not be named.
I joined a forum in 7th grade, and especially because I was an anxious, bullied kid with a speech impediment and undiagnosed ADHD, it very quickly became a safe haven and some of my most tangible community in my life.
