Well, I had a lot as a Elementary school kid. I mean a lot.
It's kinda weird to say, but I was Therian at the end of Elementary school, which means I saw myself as an animal. I imagined myself as a patchy colored anthro wolf named Andra. I had a black and grey pelted anthro wolf named Twilight as my mate, and he was one of my imaginary friends. We also had pups too. Most of my other imaginary friends where characters from books or movies, for example, Tigerclaw from Warriors and Poppy from AVI's Tales From Dimwood Forest books. I thought of myself as many different things since Kindergarden, but Andra was more enjoying to me.
Don't worry, I got over my mental issue near the end of 6th grade, when I completely hit puberty. I snapped, now believing that I'm completely Homo Sapien like I should. I came out as a furry after this identity crisis, which is less strange, fortunately. Maybe puberty is kinda helpful after all.
