Don't think the second you turn thirteen you're gonna be all "mature" you gotta enjoy these years and have fun because this is the time you find your identity, having stuffed animals is a like the thing that makes you YOU. Find who you are and a reason to enjoy life, discover what music you like and pick up an instrument or find a different hobby, such as taking up painting or sports. You need to realize that teenagers are probably sometimes less mature than younger children simply because of humor, if you lose your sense of humor you will not be happy and just live your life being a sourpuss. Just find yourself that's all I'm asking you to do πππ
