How old am I at heart?

I'm 13 years old. An 8th grader. I like to play with Littlest Pet Shops and Webkinz. But I don't have to buy them all the time because I am a big kid and I think it's weird to spend all my money on toys. So I also have other interests but I do obsess over webkinz and littlest pet shops. I watch movies and tv shows like The Wizard of Oz, Lady and the Tramp, Aristocats, Fox and the Hound, Alpha and Omega, Bolt, Milo and Otis, Homeward Bound, Watership Down. TV shows: iCarly, Big Time Rush, Sam and Cat, Victorious, Wander over Yonder, Powerpuff Girls, My Little Pony Friendship is Magic, Foster's Home for Imaginary Friends, Puppy in My Pocket, Pound Puppies etc. Music: Imagine Dragons, Evanescence, Katy Perry, Lady Gaga, Justin Bieber, Big Time Rush, Victoria Justice, Green Day, The Black eyed peas, My Chemical Romance, Miranda Cosgrove etc. I play with Littlest Pet Shops. I love kittens and puppies but mostly kittens because I am a huge cat lover. Yes, it's strange but I have 5 cats. I love panting my nails. I go on facebook and youtube all the time. I am a huge computer nerd. I have a cell phone but I only text my family members. Like my older sister who lives away. I have a huge littlest pet shop collection. I have 147 LPS pets. I forgot to tell you but I love the movie The Lion King. I know it's overrated but it's one of my favorites. I love The Lion King it's a perfect movie for kids and adults. It's really funny too. But yeah. Just tell me what age you think I am at heart.
