I did something like this when I was little. It's pathetic really. I used to daydream about imaginary planets and write down all their characteristics. Kinda like sonic fans and their recolored hedgehogs. When I was 11 or 12 I got really obsessed with one of these planets and even came up with all these little details; rivers, mountains, islands, seasons, weather, cultures, religions, cities, technologies, species of plants, I even made up my own primitive language for it. I kept "visiting" it to cope with my failures even after I started highschool, and kept taking and adding stuff from it (I made a huge overhaul in 2005 and retconned nearly every part of it's imaginary history) but as I grew older and found other sources of entertainment I stopped visiting it and nearly forgot about it completely. It all came back to me and hit me like a rock in the face when my dad tried to throw away some of my old notebooks and I didn't let him; I said I wanted to check them out first. When I read all those papers I wrote about it, all those little maps, I couldn't help but feel incredibly stupid. How could I be so dumb and spend so much time and effort on something so retarded? The worst part is that I feel very attached to it because I invested a lot of energy into it, and if a stranger were to take a look at it and tell me how much it sucks, it would devastate me. So I can't even post it online.
