When I was a kid, I liked cartoon animal stuff. So do a lot of kids, that's why they're featured in so much stuff marketed towards them. I never outgrew it. I found similar people, i talk and play games with them online. I meet up with local ones at parks/restaurants/zoos/whatever to talk, play games, get outside, or whatever. Just hangout; do something more than sit inside. I go to conventions to meet up with friends from other states. We hang out and have fun.
It's just an interest I never outgrew and just have fun with. There is no "deep reason" for me, and I can't imagine what a reason as deep as Molten is suggesting could be. If I'm feeling a little down, sure it'll help, but so will any other interest so that's not really a valid point. Sometimes I'll play a game, or read a book, or talk to a friend. But not if you're legitimately depressed like Molten said. See a psychiatrist
