It is. :) It actually started way back when I was still in school. I suffered from pretty severe depression, but being a teenager I thought I had to deal with it by myself and I didn't talk to my parents. Instead, I would skip school, take my bike and just ride off into the forest and just read all day.
Back then it was classic escapism, really.
I'm mostly better now, was in therapy for a bit and while I still have some bad days, the habit of doing this to hide away from the world has morphed into something I do just because I love it, not to get away from something.
